White-throated Sparrow

White-crowned Sparrow
(Zonotrichia leucophrys)
I am familiar with many sparrow species but my two favourites are the White-throated Sparrow and the White-crowned Sparrow. I have seen these two species over several decades whiles living in King Township, on the Oak Ridges Moraine, a few kilometres north of Toronto on the north shore of Lake Ontario.
I particularly like these two species because of their eye-catching appearance with their black and white head markings.
Both species are commonly found in my part of the world.
The White-throated Sparrow's song is a clear, whistled "Pure Sweet Canada, Canada, Canada", while the White-crowned Sparrow's song is a series of clear whistles followed by buzzy notes.
The White throated Sparrow's upperparts are streaked, with underparts clear gray. Its head has black-and-white stripes; sharply defined white throat patch and dark bill. The White-crowned Sparrow is similar but lacks the white throat patch and is slimmer, with a pink bill.
Both of these largish sparrows are approximately 6 to 7 " (15 to 17 cm.)
Both are well-known across Canada and the U.S. Generally speaking both species summer in northern Canadian forests and many winter in the lower forests of the U.S., although some White-Crowneds live all-year along the Pacific Coast.
In the case of the White-Throated Sparrow, two colour morphs are based on head-striping: field studies show that white-striped males tend to mate with tan-striped females, and tan-striped males tend to mate more with white-striped females ( see photo below)...
