Cut Across Shorty

Made a quick stop by the Nanaimo River estuary after work today and had a quick check while Jenny remained in the car and occupied herself with a sudoku (or sodoku, or soduko...).

I took a walk along the hedge, it was quiet. I scanned the marsh, it was quiet. I checked the posts and shrubs for bluebirds, phoebes, etc, they were quiet. I looked up, it was quiet.

Then just as I was about to call it a day, I nearly stood on a short-eared owl. It flew up from its temporary roost and flopped off, dropping down again approximately 100 metres away. Having not seen any owls for several days, and given the rather unfamiliar orangey appearance of this bird, I suspect it was a migrant as opposed to one of the wintering ones. Needless to say, I left it where it was.
Checking the distant small trees along the embankment, I noticed a northern shrike actively hunting.
Then I went home.

Nanaimo Estuary Springs To Life

Another fine morning, and another early jaunt down to the estuary...
It was quite hard work today though, and the saving grace provided by the impressive sight of the migrating swans and geese witnessed earlier in the week was, of course, completely absent.

nanaimo river estuary
I arrived at the end of Raines Road just before 7.30am, and other than a couple of American robins muttering away, it was all quiet. Over the next half hour it picked up only slightly, with Bewick's wrens and song sparrows adding to the morning chorus.
I had a good trundle around hoping to come across something interesting, passing through.
I didn't.
There were 3 northern harriers seen in total, the usual male and female plus a 1st year bird. There were no owls on show.
A couple of noisy belted kingfisher rattled around the area and a lone brown-headed cowbird represented the only 'vis' as it flew high over, calling. A couple of tree swallows twittered around the nest boxes.
Then suddenly, just around 8.10am things really picked up. A pair of western meadowlark appeared, and one started to sing, then it seemed as if someone had emptied a bucket of robins out, with several darting about the place.
Next up was a northern shrike, which appeared from nowhere - presumably another migrant, as there haven't been any in residence here for the last few months.
And finally, to really add a bit of spring magic, the sound of a greater yellowlegs emanated from the river, soon followed by the gangly wader itself, as it rose up and flew off over the marsh.
Despite the encouraging upsurge in activity, I had to leave and go and earn some rent money...

After work, I made a brief stop at the Nanaimo River estuary again on my way home. the shrike was still in much the same area, singing its little heart out. Sadly, the video below does little justice to its delightful, jumbled song.
The only other thing of note was a solitary short-eared owl.

Another post-work birding visit to the Nanaimo estuary

Once again the weather was kind and I managed 45 minutes at the Nanaimo River estuary on my way home this evening.
There were several hundred gulls coming in to roost at the river mouth, but I couldn't dig out anything different out from the mass of glaucous-winged, and associated glaucous-winged mutants, other than a few California and Thayer's gulls. 
A group of c50 common goldeneye were on the river, as were a handful of trumpeter swans and a few gadwall, teal, mallard etc.
Three northern harriers made appearances - adult female, male and juv.
A northern shrike was the first I've seen here for some time. Return passage bird?
Other passerines were thin on the ground, just a small flock of juncos and a single fox sparrow to speak of.
A single short-eared owl showed well briefly before heading off to hunt in the fields.

Short-lived shortie shocker

Brit readers may be interested to know that the clocks went back last night/this morning - a week later than in the UK.

So, I took advantage of the extra hour and headed off to the estuary bright and early. And when I say bright, I don't half mean it. It was glorious; blue skies, and pretty warm for 7.30am in early November!
I was quickly met by a northern shrike, busily pursuing a chickadee. Not sure of the outcome, as they vanished behind the hedge...

From the viewing platform, I could see 3 trumpeter swans out on the water. Good numbers of American wigeon were visible, though distant. Similarly, buffleheads, mallard, pintail, common merganser, and a pair of gadwall were bobbing about.
Another northern shrike was hunting from a snag out on the western marsh.
A juv northern harrier sailed by, passing over the lone shooter out on the marsh. To be honest, I don't think the ducks had much to worry about - I didn't see the guy hit a thing, despite a number of attempts.
Walking back toward the hedge, I noticed a bunch of western meadowlarks as they flew up into a hawthorn. I counted 18 in total (one of which is pictured).
I was quite surprised to see an American kestrel sat on a post out on the marsh. I expect this is the same bird as has been present at Holden Creek for the past few weeks.

I noticed something of a commotion going on some distance away, involving around 40-50 ravens. They were all flying around, quite high and seemingly excited by something.
Getting my bins on them, I noticed a short-eared owl amongst the melee. The ravens were relentlessly mobbing the owl, which was flying around in small circles, in a panicked state.
Convinced that the shortie would soon break away and head for cover, I kept watching, fascinated. Suddenly a sub-adult bald eagle flew through the flock and grabbed the owl in its talons. It flew up, mangling the owl in the progress, and then spiralled downward, eventually releasing its limp victim, which fell toward the ground pursued by a mob of murderous ravens.
Very curious behaviour, and not a little depressing!
I've seen owls mobbed by all manner of things in the past, but this is without doubt the first time I've seen such a brutal, and terminal, finale.
As I left the estuary around 9.20am I met a number of the Sunday Bird Walk participants, who had just arrived, and told them of my grizzly sighting. Hopefully their experience was somewhat less violent!

I headed around to Holden Creek for a quick scan. There were still 24 greater white-fronted geese and 33 cackling geese in the fields. I couldn't see anything unusual among the green-winged teal.
A pileated woodpecker flew over and a red-breasted sapsucker put in an appearance.
I also saw my first ruby-crowned kinglet of the fall.

Later, Jen and I went to Cable Bay. We didn't see too much ornithologically speaking but it was very pleasant.
We got good views of both seals and sealions - which is always a treat. And I took the accompanying pic to demonstrate the season... 

I popped back down to the estuary for dusk.
I didn't see any short-eared owls at all, despite waiting until it was too dark to see.  
A shrike, a juv Coopers hawk and a female northern harrier showed before the light went. A Wilson's single snipe flew over, only detected by its distinctive call.

Eurasian wigeon joins yanks

Jenny and I took a stroll down to Jack Point late morning.
We didn't see too much in the way of birds, but out on the water I saw my first buffleheads and horned grebes of the season plus good numbers of red-breasted mergansers, several common loons, and one Pacific loon.

We dropped by at Holden Creek on the way back.
The greater white-fronted and cackling geese were still in the fields. A scan through the 300, or so, green-winged teal revealed just a handful of mallard, pintail and American wigeon. Given how few wigeon were present, I was surprised to find a drake Eurasian wigeon. I wonder if there are more among the 500+ American wigeon out on the estuary?
A greater yellowlegs flew in.
The American kestrel was hunting in the fields, as was a northern shrike. Two northern harriers were quartering the marsh. A pair of belted kingfishers were charging noisily around the area.

Later I stopped off at Quennel Lake. Not too much going on, just a couple of lesser scaup, a drake Barrow's goldeneye and my first post-breeding American coot. The soon-to-be flooded fields at the northern end of the lake had attracted a pair of trumpeter swans, plus a small flock of white-fronted geese.

Pretty birdy morning.

It was a bright morning, and the hunters were thin on the ground, making my visit to the Nanaimo River estuary rather enjoyable.

One of the first birds I saw was the northern shrike, sat in the large oak. There were lots of juncos, song sparrows, and golden-crowned sparrows in the vegetation around the area. A small flock of chestnut-backed chickadees had, sadly, failed to attract any transient warblers or similar.
A single Lincoln's sparrow was in the large hedgerow.
From the platform, I could see a single mute, and a pair of trumpeter swans, plus large rafts of American wigeon out on the water. A gathering of some 62 bald eagles was quite impressive.
At least 3, probably 4, northern harriers, including a male, were seen hunting over the marshes. A large Cooper's hawk flew through and an adult peregrine spooked the wildfowl over the estuary.
Met Ralph Hocken, who was getting some superb shots of the harriers. As always, it was good to stop and have a chat with Ralph - I eventually left him to his photography, and headed off to Holden Creek for the high tide. 

The goose flock was still present in the near field, comprising 116 cackling and 96 greater white-fronted.
The male American kestrel was still hunting around the fields (see rubbish video below). Might this bird stick around for the winter? A further couple of harriers were seen - presumably two of the same as seen earlier.
Large numbers of green-winged teal were dabbling out on the marsh, along with a handful of wigeon.
3 killdeer flew over.

Brief visit

Just squeezed a dusky half hour down at the Nanaimo River estuary this evening on my way home from work.
A northern shrike was hunting from the 'bluebird posts', and a solitary juv northern harrier was hunting nearby. A single Lincoln's sparrow was the only notable passerine.
The number of eagles continues to build, with 20+ out and about.

Hopefully I'll get a chance to give the place a good grilling tomorrow... maybe turn up some meadowlarks, if nothing else?

Swan-ee River

Spent the first 40 minutes or so of daylight down at the Nanaimo River estuary this morning.
On the way to the parking area, I pulled over for a quick look at a group of 18 Barrow's goldeneye, new in on the river.
Going through the many, many glaucous-winged gulls on the shingle banks, I picked out a 'decent' herring gull. Small numbers of Californian gulls were floating around over the marsh.
From the viewing platform, I could see large rafts of American wigeon at the estuary mouth, while green-winged teal, mallard, pintail, common merganser and hooded mergansers made up the remaining wildfowl.
A small flock of cackling geese passed over, and the large white blob floating on the sea turned out not to be my first wild swan of the season, but a mute swan. Pah.
3 different northern harriers made appearances, and the ever-singing northern shrike kept me entertained while I scanned the marshes.
A noisy greater yellowlegs, eventually showed, and flew off in the direction of Holden Creek. 
I couldn't locate anything out of the ordinary among the small flock of chestnut-backed chickadees, or various sparrow groups.

After work, I returned to the estuary. In the half hour of fading light, I clocked a single juv northern harrier, and the short-eared owl emerged just after 6pm. It showed well again, and even treated me to views of effortless vole catching.
My disappointment at finding that crappy mute swan this morning was eclipsed by the sight of 13 trumpeter swans flying over, heading south.

Asio like it...

Managed to squeeze in a visit to the Nanaimo River estuary on my home this evening, and just about caught the last half hour of decent-ish light.
A quick scan through the gulls revealed nothing of earth-shattering note. Good numbers of common merganser were on the swollen river.

As I walked toward the large oak, a distant bird caught my eye at the back of the meadow; it turned out to be my first short-eared owl of the winter. Nice. (The pic shown here was taken last winter, by the way).
According to Sibley, it fitted the description of a male, but I have to concede, that his is the only book that I have ever seen that makes reference to the identification of sexes in the field. Even Claus Konig and Friedhelm Weick make no mention of sexual dimorphism in their Owls of the World... what's the deal here?
I watched it hunting for a couple of minutes then headed to the platform for a scan of the area.
A pair of northern shrikes were chasing each other around, doubtless establishing territories for the winter.
Adult male and female northern harriers were hunting over the marsh to the west of the river, while a juvenile was hunting along the long hedge. A further adult female came onto the marsh from the fields to the south of the area.

Before it got too dark, I headed along the hedge where I got ace views of the short-eared owl as it hunted, and it even came to check me out before landing on a post and posing nicely.
Well, it may have only been half an hour, but it certainly set the pace for the next few months of winter birding on the estuary!

Early trundle

I managed to get up in time for a trawl around the Nanaimo River estuary for the first hour of daylight this morning.
It was very peaceful, and I loved having the place to myself.
What was presumably the same northern shrike that I came across yesterday, was singing from a prominent perch along the long hedge. After a short while, it flew off to mob a juvenile red-tailed hawk that was sat on a post out on the marsh. Curiously, the alarm call that the shrike used, sounded a lot like a dunlin!
I could hear a Wilson's snipe calling from somewhere, and I later saw one being relentlessly targeted by a persistent peregrine
Pintails were coming over in small groups, and large rafts of American wigeon were out on the water.
Both the male and juvenile northern harrier were hunting around the area.

Shrike a light!

Yesterday's attempt at a bit of post-work birding at the Nanaimo River estuary was scuppered by the rolling fog that reduced visibility considerably. Also, a couple of local rifle-toting teens were shooting at anything that moved, and I didn't much fancy being one of those anythings...

This evening was slightly better, in as much as I could actually see a little bit, despite the fading light and onset of rain. Also, the absence of guns was an improvement. There wasn't much doing, however.
A curious bubbling song led me to a nice northern shrike singing away from the tangled depths of a hawthorn near the 'kidney pools', but other than that it was pretty quiet.
With a wet weekend forecast, I can't imagine the next few days being too exciting... maybe some passage stuff will get grounded? Let's see.

Benefits of jet-lag...

Still a little upside down from the effects of jet-lag I woke pretty early and decided, after an hour of tossing and turning, to go for a wander around the Nanaimo River estuary.
Naturally, I had the place to myself for the first couple of hours of daylight.
The various sparrow and finch flocks were rather small and scattered and consequently pretty difficult to go through systematically. However, a concerted effort revealed little among the juncos, house & purple finches and golden-crowned & song sparrows. There are very few white-crowned sparrows around now, all juvs, and the only other species seen were two Lincoln's sparrows, and singles of savannah and fox sparrow. The latter was singing.
Several parties of red-winged blackbird passed over, with a few dropping in. 
A pair of merlin and a Cooper's hawk were doing their best to disrupt my passerine search...
From the observation platform I could see a group of 8 adult snow geese out on the marsh to the west of the river mouth.
Good numbers of American wigeon plus a few mallard and common merganser were on the river, as was a single hooded merganser. 6 killdeer were gathered on the gravel bank.
A single Thayer's gull was among the many glaucous-winged gulls on the river.
I accidentally flushed long-billed dowitcher from the creek behind the long hedge.

Mid-afternoon, a quick stop at Holden Creek revealed a flock of some 90 geese, a mix of white-fronted and cackling plus a lone adult snow goose.
Better still, however was my first northern shrike of the autumn.

Wetter is better...

Despite, or rather thanks to,  the almost constant drizzle the morning's birding at the Nanaimo River estuary was pretty good today.

The 'new' northern shrike was still in the same area as yesterday evening, and was entertaining me with a collection of extraordinary sounds - I don't believe I've ever heard this species sing before, what a weird bunch of sounds! It's a rather pale bird, and has a striking, almost pure white, rump in flight.

A female northern harrier was sat, soggily, on a snag in the fields.

The rain had obviously dumped a few birds and I was aware of an increase in the number of white-crowned and savannah sparrows around the place. Also, I came across a trio of Lincoln's sparrows.
There were several orange-crowned warblers feeding along the long hedgerow, plus a pair of yellow-rumped. Then I bumped into a fall of yellow-rumped warblers - all males, totalling at least 16 birds, of which 5 where 'Myrtles'.

The hirundine numbers were through the roof and there were approximately 500 feeding over the river. I picked out at least 1 cliff and 2 barn swallows from the mass of violet-greens, plus around 5 tree swallows. I was nearly fooled into thinking I'd seen northern-roughed winged by a couple of very drab female violet-greens. At one point the swallows were spooked by a passing peregrine, forcing them up into a whole whirling mass - quite impressive.
Then, just as I was about to give up, I noticed a very dark, larger, bird coming in - it was the first of a group of 6 purple martins. They came over the river, never really joining the other birds, and passed by me on the viewing platform at eye level. Cool. Not a new bird, but a BC tick.

I decided to have a quick look at Holden Creek on my way home. No sign of any pipits or waders out on the marsh. Another 100 or so violet-green swallows, and 3 barn swallows, were feeding over the fields. A red-tailed hawk was sat out on a small tree.
Of interest, a very bright fox sparrow was here too. Much 'redder' than any I've seen previously on the island and suggestive of what Sibley refers to as 'slate-coloured' - is this a form often found here on passage?

Bright & breezy...

It was very bright this morning down at the Nanaimo River estuary, and relatively calm behind the long hedge... Darned breezy, and nippy, when out in the open though!
Not too much evidence of movement, with just 1 yellow-rumped warbler showing - nothing to suggest that this was newly arrived.
Savannah sparrows, again, were all over the place and a northern shrike was hunting from the posts.
Several juv. bald eagles were floating around, and a sharp-shinned hawk scattered the crossbills and siskins by the viewing platform.
A couple of white-fronted geese came over.
The greater yellowlegs on the river, now number 13.

Didn't feel especially spring like....

No blue Monday

Had a post work trawl around a very quiet estuary this evening (6pm-7.30pm).
No sign of the mountain bluebird. I suppose conditions last night were suitable for it to have cleared off...
There weren't even any savannah sparrows to be seen or heard - was the recent influx made up of northbound, off-passage birds?

A northern shrike was hunting from the hawthorns in the fields and a couple of flickers were kicking around.
A single white-crowned sparrow was singing away, but there were no crossbills or golden-crowned sparrows around.
The tide was way out, as were the gulls and wildfowl...
8 greater yellowlegs (one of which is pictured here) were on a shingle spit on the river.
Good numbers of violet-green swallow and just 1 tree swallow were whizzing around.
As usual, a few bald eagles were cruising around.

Bluebird of happiness

Managed an early morning visit to the Nanaimo River estuary, before being encouraged to go for a nice day out on Saltspring Island - a place where I consistently see no birds of interest.

Anyway, upon arrival it was apparent that there were good numbers of savannah sparrow on territory, with birds singing from every available spot. I was surprised to rediscover the golden-crowned sparrow flock (14 birds) and the attendant white-throated sparrow, which I'd assumed had departed. An influx of white-crowned sparrows was also evident, again a number of birds were in song.
A group of violet-green swallow were roosting in the big oak (see pic.).
The mountain bluebird was still present out on the posts. Presumably the same bird, despite my not seeing it yesterday - it must have been keeping its head down.
A check along the hedgerow revealed just 1 female yellow-rumped warbler.


There were good numbers of red crossbill (see pic), including recently fledged young, around - plus a couple of pine siskins.
I could hear yellowlegs, frequently calling from somewhere on the river but I didn't spend any time looking for them. Noticed a handful of gadwall dabbling around the waterlogged fields.
Left the site around 8.30am and decided to check Holden Creek. No sign of yesterday's white-fronts, or even the Euro wigeon. A single northern shrike was hunting along the creek, but otherwise it was pretty quiet. As usual, there were plenty of green-winged teal present, plus 3 hooded merganser.

Owls about that...

Following a very pleasant day doing family stuff, I found a window of birding opportunity in the late afternoon, so I headed - guess where - yep, you guessed it, down to the Nanaimo River estuary.
It was pretty cool and showery, and I had the place pretty much to myself. There was one other person there, wandering around in a small area of riverside marsh carrying a clipboard, tape measure and field guide of some kind... I guessed from his behaviour, he was engaged in some kind of botanical survey? Unfortunately, our paths didn't cross, so I didn't get to ask him.

Again, a pair of red crossbill were showing really well, this time also accompanied by 3 pine siskin, in the small trees (crab apple?) near the viewing platform.
Heading up the long hedge, I came across a short-eared owl - the first I've seen here for quite some time.

A northern shrike was doing the rounds and a few violet-green swallows were moving through.
The hedge was quiet with just the 'resident' towhees, song sparrow and Bewick's wrens present.
A savannah sparrow was again in the weedy area near the gorse patch. Not sure if it was the same bird as yesterday, as it seemed brighter and better marked, with a much 'warmer' tertial/secondary patch.

Retracing my steps back to the viewing platform I noticed a cloud of hirundines feeding over the river mouth. Scanning through the 200 or so birds, they all appeared to violet-green swallows.
Then a tell-tale call alerted me to a Wilson's snipe - it flew up off the marsh on the other side of the river and rose high over me before flying out and plummeting down back onto the saltmarsh. When I say, 'tell-tale call' I mean I knew it was a snipe, not that I could distinguish it specifically as Wilson's, as opposed to common... I'm sure you know what I mean...

With it being high tide, at least the gulls and wildfowl were close enough to scope through - though, I couldn't find anything to get excited about.  

Oh, of note: we had our first red-breasted sapsucker in the yard* this morning.
* UK readers may wish to know that 'yard' in Canada means garden... not, like a back yard in Britain. And a shop is a shed, and a store is a shop... there's probably an entirely different blog in this...

Tasty sandwichensis...

It was a touch cool & breezy down at the Nanaimo River estuary this morning, but there were at least a few more birds around.
Unfortunately, the gulls and ducks were, again, miles away so there was no chance to give them a grilling. So, armed with little other than a heap of optimism, I went for a trample around looking for migrants.
I was swiftly rewarded with views of my first savannah sparrow of the year (pic right). My starter for ten so to speak, as this is a very common species - just not so in winter.
A northern shrike was hunting from the scattered trees out on the marsh.
Then I heard the distinctive and delightful call, of what was a new patch bird for me. Yes, the evocative sound of the magnificent pheasant. Hmm.
Back to proper birds, and a few violet-green swallows were moving through, though an hour's bush bashing failed to reveal any other migrants.
A single female crossbill turned up and posed nicely for a while.

I decided to head around to Holden Creek for a peek. The fields by the creek were teeming with American robins - at least 100. And, not one, but two more northern shrikes were hunting from the barb-wired fence. A flock of 30, or so, violet-green swallows were feeding over the fields.
Only a few green-winged teal and a couple of mallard were out on the marsh. More crossbills and a couple of siskin were scooting around. A pair of red-tailed hawks were out hunting, or seeing off passing bald eagles, while a female northern harrier was being bothered by a raven.

Patch lowlights

It was pretty quiet down on the Nanaimo waterfront at lunchtime today, single pigeon guillemot and common loon offshore the only things of note.
A Bewick's wren was singing from one of the ornamental conifers, and the male Anna's hummingbird was perched up in his regular spot.

On my way home from work I noticed a merlin in pursuit of a starling over the highway near Petroglyph.
I went straight to the estuary for an hour, but it was painfully quiet. The ducks and gulls were miles out, with the tide, and there were no songbirds to be seen or heard at all. And I mean none. Not a song sparrow, not a towhee - nothing. In fact, other than a multitude of ravens, there was nothing until a lone flicker appeared. Its starring role was soon eclipsed by the appearance of a northern shrike - phew!
I need a better local patch...
Back in Blighty, I would have been trampling along the Lune estuary flushing smart wheatears and hearing chiffchaffs singing from the hawthorns on a day like today - mind you, I can't remember ever finding an American kestrel down there, so I suppose it's all relative!

Gulls just wanna have fun

Headed up the island a wee bit today for a grockle's day out. After a trip to Coombs, we dropped by Parksville to have a cup of tea at Rich & Lori's before heading out, Rich in tow, to see if we could find a slaty-backed gull. Two of these Asian vagrants have been seen recently, amongst the mass of birds along this stretch of coast, here for the annual herring spawn.

We went first, to French Creek. Offshore there were hundreds of long-tailed ducks & surf scoters, while there were almost constant fly-by's of birds, including numerous white-winged scoters. There were a few gulls on the beach, amongst them the commoner species: glaucous-winged, California, mew, and a cracking adult ring-billed gull - I think this may be the first RB gull I've seen on the island..? A large 1st winter glaucous gull dropped in, dazzling white. Guy Monty and Donna had arrived to do some gulling too, so we had a bit of a chat before heading round to another stretch a short distance along the coast where Guy informed us a mass of gulls were gathered.
We arrived to find the water's edge teeming with brant and gulls. Another glaucous gull was quickly found as we scanned through the birds, in search of something with a dark mantle. Today was not to be the day for such exotic rewards, but we thoroughly enjoyed the spectacle.

Back in Cedar, Jenny and I paid a quick visit to Quennell Lake for an early evening check. Still 70ish shoveler present, but only a few pintail and American wigeon. There was no sign of the large number of common mergansers that have been a feature of late, and only a handful of bufflehead.
There were, however, around 200 hirundines feeding over the lake - a mix of tree and violet-green swallow (approx. 70/30 respectively).
A northern shrike was hunting from a fencepost in the nearby fields and the single cackling goose was with just 36 Canada geese. A merlin flew through.  

Stop Press: we were obviously in the wrong place yesterday - see Mike Yip's pics of slaty-backed gull here: http://vancouverislandbirds.com
