September 5 2012. Ruthven Park, Cayuga ON.  At the end of a day I’ll often ask myself: What was the one bird, above all others, that made me think Wow?  What was the Bird of the Day?  Well, today it was vireos: Warbling, Philadelphia, Red–eyed and Yellow–throated; we encountered them all and they all made me smile.

For reasons that I can’t quite explain, I like the vireos, maybe because they can be so challenging to identify visually, maybe because of their endless summertime songs, or maybe it’s their “I may not be very colourful but I’m here.’ approach to life.

Yesterday’s unsettled weather, which produced torrential rains not very far from us, moved out overnight.  At first light this morning patchy fog hung low over the bird observatory and we wondered what species might have left and what might have come in to replace them overnight .

Quite early while the fog still hung low, we could hear a Yellow–throated Vireo singing in the woods behind the banding lab.  They have a rather hoarse and throaty song that is ably described in Pete Dunne’s excellent book as: “Lazy whistled song is a series of alternately higher then lower two-(sometimes three)note phrases separated by a pause. Twee’ree (rising) he’yew (falling); twee’lree(rising) or he’yew….the overall quality is hoarse and slurred – a vireo with a sore throat.”  We always have a few Yellow-throated Vireos nesting in the wooded ravines near the observatory, they kind of anchor the woodland.

Later on this morning we started seeing Red–eyed Vireos and ended up banding a dozen or more, all youngsters hatched this year.  This is a bird that dresses like a hung-over courtroom lawyer, somber grays, beiges and off white, with red eyes framed by immaculately trimmed eyeliner; very handsome.  On territory it sings endlessly all day and continues well into August.  To me, like sweet corn and peaches, the Red-eyed Vireo is a part of summer.

The Red-eyed Vireo’s song is almost identical to that of the Philadelphia Vireo, a rather hard to see, hard to find little bird. We agreed that the Philly’s plumage is so unremarkable, so devoid of defining field marks except for a beautiful wash of pale yellow on the breast, that sometimes a yellowish summer bird with nothing much to distinguish it may turn out to be a Philadelphia Vireo.

Lastly, Warbling Vireos were singing as if it were June.  We banded one or two this morning, but I encountered several while doing the daily census.  The census trail leads along the bank of a wide, shallow river and at one time I could pick out 2 or 3 Warbling Vireos singing from the bordering Hackberry trees.  Their song is a frantic scramble of sweet notes, very hard to describe, but a friend once sent me this description of it: “If I sees ya I will squeeze ya an I’ll squeeze ya till ya hurt”.  Say that a few times fast (there’s no punctuation, so no pauses) and you’ll get something like the cadence of their song.

The only likely Ontario vireo missing today was the Blue-headed Vireo,  probably the most strikingly marked of the lot.  But it’s the only vireo for which I have a photo, so here it is from two years ago.  Just banded and about to be set free.

September 4 2012. Ruthven Park, Cayuga ON. Back early to the bird observatory today, they’re a little short handed and well, it’s interesting and always challenging.  The weather had deteriorated since the summer glories of the past week or so, rain threatened all morning today and even went so far as to dampen us with a mid morning shower; a nice warm one though.

I started the census at 08.45 but had to abandon it after half an hour or so when the shower struck.  The birds must have known something was up and left town because in that half an hour I only counted 11 species. Once the rain had passed over I restarted and turned up 29 species including a couple of Purple Finches, a small and agitated group of Philadelphia Vireos high in the treetops and a nice Eastern Kingbird sitting atop a dead tree watching over the world below.

Towards the end of the morning we found and banded a young male Hooded Warbler.  He was without doubt my Bird of the Day because absolutely nothing else today, not even a couple of Blackpoll Warblers, Common Yellowthroats or Wilson’s Warblers, came close to delivering the same OMG impact.  (Take a look at the observatory’s blog here) Hooded Warblers are uncommon in Ontario, there are small pocket populations around the west end of Lake Ontario and along the north shore of Lake Erie.  But in the central eastern states of the U.S.A it is a fairly common breeding bird.

Any human as striking and stunningly pretty as this bird would surely quickly make his way to become a preening and self-important celebrity.

September 3 2012. Ruthven Park, Cayuga ON. I had quite forgotten what a richness of bird species there is to enjoy on a good day at a good bird observatory.  Today was my first opportunity to return to my favourite bird observatory to lend a hand this the fall season.  Bird observatory activities including census taking, mist-netting and banding continues daily throughout September and October.

To refresh, the observatory is located in the grounds of a splendid 19^th Century neo-classical country house that would look quite National Trustish in England but is little short of jaw-dropping in 21^st Century Ontario. The grounds include several acres of wide alluvial river flats, a network of heavily wooded creek valleys, open farm fields and upland forests. This is perforce a very brief introduction; you can read lots more about it and get completely absorbed for hours by visiting its website here and nature blog here.

On my arrival early this morning it was already busy and I was put to work banding a young Scarlet Tanager.  Then a check of the nets turned up Red–eyed Vireo, Philadelphia Vireo, Winter Wren, Yellow–billed Cuckoo, Magnolia Warbler and Ovenbird to name but a few of what I remember.

It sometimes/ often / usually /always falls to me to do the daily census.  A task that keeps me out of harm’s way for a couple of hours and fills a page or two with a list of all birds seen or heard on a walk around a prescribed route.  I am usually accompanied by visitors, sometimes they’re birders, sometimes not, but many eyes and ears are always helpful.

Today we had some great sightings; a single Yellow–billed Cuckoo (not the one banded just before we left the banding lab), many Eastern Wood Peewees singing.  A couple of Red–eyed Vireos were in the sparse branches of a dead spruce and close to about 20 Cedar Waxwings feeding on the abundant blue-grey fruit of a Red Cedar. Along the river a family of four, maybe five, Osprey were patrolling up and down, the parents looking for food to keep their insistent youngsters happy.  A pair of Wood Duck flew by and then shortly afterwards three Green-winged Teal.  On a gravel-bar in the river were 16 Killdeer, 2 Lesser Yellowlegs and a single Spotted Sandpiper.  Then, perhaps the event of the day, an adult Bald Eagle closely chased one of the Ospreys pressing home a point of proprietorship that I never did figure out.

My Birds of the Day were three Chimney Swifts seen circling above the banding lab. Swifts always make me stop and stare because they are irrefutably birds of summer, always flying in high-wheeling chase above us, twittering busily and living a perpetually airborne life.  If given the chance I think I’d like to be reincarnated as a swift.

August 31 2012. Lowville ON. We decided to see what early migrants we could find along a quiet, well wooded river valley.  And except for the rather brisk wind, it was really quiet; the trees and understory plants seemed to have had enough of summer and drought.  Still, there were some interesting birds around.  One of our first finds was a couple of Scarlet Tanagers, both dingy olive-green: an adult female in scruffy molt and an indeterminate youngster. Several Magnolia Warblers, distinct with their bright and faintly streaked yellow breasts, more-or-less eye ring and sharply black-and-white underside of the tail.  My companion with his sharp young eyes also found a Yellow–bellied Flycatcher, a Canada Warbler and a Ruby–throated Hummingbird.

At a break in the tree canopy we looked up to see a soaring hawk wheeling above us which we both immediately took as a Red-tailed Hawk, but as it turned and fanned its tail I could see horizontal bars across it.  Not  Red-tailed Hawk at all, this was a young albeit rather colourless, Red–shouldered Hawk.  Red-shoulders are not rare but they’re not common either; they breed in our general area but their preferred habitat of large expanses of wet woodlands has become increasingly scarce.  Our populations of Red-shouldered Hawks are seasonal migrants and winter in Texas and farther south into Mexico.  But perhaps they prefer to be around here as they are one of the first hawks to return in March while there’s snow on the ground, and the reflected illumination off the snow lights up their robin-red under-wings to dramatic effect.  It was my Bird of the Day even though we ended our hot walk with a close encounter with a Sharp–shinned Hawk and a fleeting glimpse of a stubby- bodied rounded-winged bird flying high and fast overhead, an American Woodcock I believe.

August 30 2012.  Long Point, ON. An on-again off-again family task took me to Lake Erie today and to one of Canada’s best birding hotspots.  Bird Studies Canada operates bird observatories at Long Point, one out on a tip of land in the middle of Lake Erie, another one close to a heavily used camping, cottage and party area.  We spent an hour or so at the latter observatory and watched the team of volunteers checking the mist nets, extracting trapped birds and banding them. While we watched they handled two or three of Black–throated Blue Warblers, a couple of American Redstarts, a young House Wren, a Magnolia Warbler and a Red–eyed Vireo.

At a marsh lookout platform we watched a female Marsh Hawk quartering the wide expanse of cattails and sloughs, and far in the distance a large group of Turkey Vultures was circling and playing in a column of rising warm air.

A stop at some sewage lagoons turned up some interesting groups of shorebirds, mostly Lesser Yellowlegs and Least Sandpipers with a couple of Pectoral Sandpipers for variety.

Out in the deeper water a dozen or so Lesser Yellowlegs were swimming and behaving like phalaropes, which was at first rather confusing because three Red-necked Phalaropes were nearby, also swimming and also, quite properly, feeding like phalaropes.  The confusion was cleared when the yellowlegs rejoined their companions and I was then able to concentrate on the phalaropes and make out the rather fine distinctions between these Red-necked Phalaropes and the Wilson’s Phalaropeof a couple of days ago.  The adjective ‘Red-necked’ only truly applies during their brief courtship and breeding season of April, May and June, otherwise they are mostly grey and white, and strikingly similar to the Wilson’s.  A fairly bold smudge of black behind the eye marked these birds as Red-necked.

Just because I’d never knowingly seen them before, these fascinating Red-necked Phalaropes were my Birds of the Day.
