I like sparrows. I like observing them, reading about them, grappling with species and subspecies identification, and even—on a good day—talking about sparrow taxonomy. The book does not include House Sparrow, an Old World sparrow that belongs to a completely different bird family. Scope of Book. Mexico border.

One website states that only 15% of the birds that hatch make it to become first year breeding adults, 6% make it to the second year, and 3% to the third year. Other species – such as starlings or t**s – stealing the nesting site of Eurasian Nuthatches is one of the major reasons for breeding failure.

In July 2011 a Henslow’s Sparrow was found in Ames, N.Y., Although Henslow’s had been reliably found in nearby Sharon Springs for many years, the last documented sighting was in 2008, and the sighting startled longtime birders, waking them up to the fact that breeding sites in the state were rapidly being lost.

That still leaves 11 Warblers that breed in Michoacán. But my experience suggests there is a fair amount of geographical overlap between the two ranges in my area. Like the Common Yellowthroat , the Yellow Warbler breeds no further south than the central Mexican highlands. It does breed in the U.S. But do they warble?

A breeding bird atlas is a special kind of book. For birders, it’s the extremely large book, shelved in a place where it can’t crush the field guides, used to research the history of a bird in their area. Corey did just this in this 2011 posting about Vesper Sparrow Pooecetes gramineus in New York State.

Seaside Sparrows were singing on both sides and occasionally popped up to give us a view before diving deep back into the Spartina grass, hopefully getting ready to nest. Seaside Sparrow. At the end of the road, we found two Nelson’s Sparrows who quickly flew out to a tiny bit of land in the channel. Eastern Meadowlark.

Fortunately, there are a few more such breeding species than most Shanghainese are aware of. While the HBW states that it breeds at 300 – 2450 meters, in Shanghai – where such elevations are not available outside of the upper floors of a few highrises – it makes to with an altitude of about 0 meters as well.
