Spotted Towhee


There are many things I love about my 'home and native land'--the way people so many people call out thank you on the bus here in Vancouver comes to mind--but probably one of the best things is that I have a 90% chance of seeing one of a pair of these beauties on my short walk from bus to office in the morning.  There's a hedge just outside my building and invariably a towhee is hopping around in there.  Given the fairly obvious difference in head color (females are brown, males glossy black), I feel quite confident in identifying which of the pair I am seeing.  I keep hoping to see some streaky babies...I can't imagine a better addition to my Towhee sightings!

Unlike most of the birds that pose protracted identification challenges for me, the Spotted Towhee is really quite easy--especially for a sparrow (think of distinguishing Cassin's and Botteri's.... or the various subspecies groups of Dark-eyed Juncos).  Even in flight, Spotted Towhees are recognizable by their big white tail spots, visible from afar.

Their call could potentially be confused with that of the Catbird, but because the latter are very rare here on the West Coast, I assume Spotted Towhee unless proven otherwise (I suppose that is a sign that I am no longer quite a beginner--I have lost the conviction that I am seeing something incredibly rare every day!).

Maybe the ease with which I can identify Spotted Towhees is the true source of my partiality for this large sparrow, but I like to think that it's more due to the bird's good looks and the attention it pays me at the beginning of my day.

My Vote for the National Bird of Canada



Lincoln's Sparrow was first described in CANADA: in Labrador by Audubon and named for a CANADIAN, Tom Lincoln. Apart from being the most beautiful sparrow in my opinion, Lincoln's is found in all the CANADIAN provinces and territories. Though initially people might hesitate to choose a sparrow as a national bird, Lincoln's Sparrow's distinctive features and beautiful song will, I am sure, encourage people to make the effort to learn one more bird.

Red-tailed Hawk--the current frontrunner--would be a disappointment as the bird for CANADA. It was first described in Jamaica and its scientific name, Buteo jamaicensis, reflects that.

Ring-billed Gull


Gulls have always been tricky for me--it seems that they have more plumages than other birds (first/second/third year; juvenile, adult, breeding/non-breeding...) and, frankly, too many of them are white, black and shades of grey.  Heermann's Gull is probably my favourite simply because I have seen them only in breeding plumage when their bills are so red that you can't mistake them for any other gull.
I was pretty good at distinguishing Ring-billed and Herring Gull, too, as they were the ones I saw most in New Jersey.  They were frequently in mixed flocks and  I learned to distinguish them by size comparison (though I admit that I also used leg color despite my usual prejudice against color as an identification criterion).  The Herring Gulls were reliably larger than than the Ring-billeds, in fact they were generally the largest gull around.  Now, however I find myself with a new set of gulls: both Herring and Ring-billed Gulls are not our 'local' species anymore (though they do occur).  You can understand my joy, then, when the other day I saw this fellow--and immediately welcomed it as a long lost friend.  Sadly, this individual is probably not long for this world--he was definitely weak and sickly which allowed my husband to get to close with the camera--but nonetheless, he had the yellowish legs, the ring on the bill and--joy, oh bliss, I discovered that Ring-billed can maintain its position of 'smaller' gull when I compare it to our current local resident: Glaucous-winged Gull.  So, by default, Ring-billed has started me on the way to learning another gull...

Northern Shrikes

Just when  I thought I'd safely categorized Shrike--versus Northern Mockingbird--I find that I am in the range of Northern Shrike instead of Loggerhead and they're not the same!  At home in Tucson, we're in the range of Loggerhead Shrike--only--but now that we have crossed the international border to the north, we are in the land of Northern Shrike and my learning has to expand, eh?
On a first glance the two Shrikes are pretty similar--and I may be forgiven for enthusiastically calling "Loggerhead" upon our arrival in BC.  The silence from my driving companion--a veteran birder of thirty-five years--assured me that I had made a mistake.  I looked again (in fact I turned around and stopped the car) and observed the bird more closely, that is I stared at the head.  The head appeared to be rounder than usual and the eye mask was rather limited--projecting only behind the eye and not extending across the forehead.  Also, this bird had a white forehead where the Loggerhead has a black one--a distinctive feature, IF you can see it.
So, it's not much to go on--both Shrikes perch in similar locations and both sound--at least to me--similar, but if you pull over and gaze next time you're in the presence of a Shrike, the chances are you'll get it down to species as long as you're in Arizona or British Columbia, and as long as you're not witnessing the first record of Brown Shrike in BC!

Shrike, are you mocking me?



When I get a nice, up close look at a Loggerhead Shrike such as this one I simply enjoy the view--and am grateful that I am not a lizard, rodent, bug...you get the picture. But when I see said Shrike from a distance, I find it rather easy to be mislead into believing that I am seeing a Northern Mockingbird. Color and pattern are similar--grey with a white wing patch; perch location is similar--tops of trees; and topography is similar--open fields. (Shrikes do appear in urban settings, but far less frequently than Northern Mockingbirds, so I am usually pretty careful before claiming to have seen one in the city).

With experience--and magnification--they really aren't all that similar. Their Gestalt is in fact rather different. While the Northern Mockingbird (and yes, there are southern Mockingbirds--but none are called Southern Mockingbird) is long and slender, the Loggerhead Shrike is long and rather rectangular. In addition, Shrikes in general have large, fat heads while Northern Mockingbirds have rather flatter, smaller ones (all this in comparison to their respective body sizes). The bill shapes, too, continue this distinction as the Shrikes have rather fat, hooked bills while the Northern Mockingbirds have slimmer, thrush-like ones. Lastly, their calls differ: the Loggerhead Shrike has a buzzy one while the Northern Mockingbird sounds more like a 'chack' 'chack'. Most helpful, however, is their song: while the Shrike has a repetitive, buzzy note, the Northern Mockingbird indulges in a wide variety of songs--from mimicking car alarms, to alarm clocks, to mourning doves...you can pretty much count on the fact that if you hear a 'weird' song, you're listening to a Northern Mockingbird. Now a real challenge would be an urban Shrike being imitated by a nearby Northern Mockingbird....I'll post that if it ever happens!

American Kestrel


I'm not really quite sure what 'home' is -- as a Canadian, I feel that I've come home in moving back to Canada; yet, on the other hand, my house is south of the border--in the land of American Kestrels.  Well, we do get American Kestrels here on the Vancouver Coast--and no, my patriotism does not extend to re-naming them Canadian Kestrels--but they are much farther and fewer between.  I generally see these smallest of the falcons of the US and Canada when I am at my US home--they tend to perch on the telephone wires just like the one above.  In my experience, I have found the females are usually visibly bigger than the males, though on checking my observations in the Nat Geo Complete, I find that the sexes are of a similar size.  But then again, comparative size only works when you have two birds of opposite sex!  Therefore I have had to learn the other distinctions between male and female. The most obvious is color, of course--the males have blue wings while the females have brown ones, but one can't always see the wings (or the light's bad...).  The difference in chest pattern (spots for the male, streaks for the female) is the distinction I find most reliable, as it's frequently easily seen from a distance.  In addition, it's easy to remember as the female also streaks, or rather bars, on the tail, while the male just has the tail band.  All these differences mean that 9/10 times I can sex the bird correctly and quickly--now I just have to get more of them to fly up north so I can keep my eye in.

The Juncos, aka The Birds



I have always thought that Hitchcock cannot have been very familiar with Yellow-eyed Juncos, for surely they inspire more fear than crows do. Their psychotic yellow eyes gleam out at you, and despite the bird's overall small size, I always get a shiver.

So sometimes I try to ignore the eyes and focus on the rest of the bird in order to identify it (and save myself from shivering).  Typical of the Yellow-eyed Junco is of course the red back that spills over into the wing coverts and tertials, distinguishing this species from the Red-backed and Gray-headed subspecies of the Dark-eyed Junco. In addition, the Yellow-eyed has a high-pitched, thin call with a rich, varied song--while the Dark-eyeds seem to sound more robust  in their calls but not as complex in their songs.

Lastly, I go by how tired I am from the hike!  If I am really tired and have attained great heights, I suspect that I am in Yellow-eyed range, whereas if I am still fresh then I conclude that I am more likely to be in Dark-eyed range.

At the moment I'm living in Vancouver, and thus I am far out of Yellow-eyed Junco range and don't need to fear that they'll flock my house and go for my eyes....
