Flight Paths traces the history of migratory research in nine chapters, starting with the earliest attempts to track birds, bird banding/ringing (which she traces back to Audubon), and ending with ‘community science’ projects such as Breeding Bird Surveys and eBird.

Though the third-most densely populated county in the United States (as of the 2010 census, thank you Wikipedia), about 25% of Bronx land is open, public space. The authors’ detailed delineation of problems with the accuracy of NYC breeding bird surveys or with the limits of historical writings may test a reader’s patience.

Penguins are flightless, but some species locomote over long distances on antarctic ice to travel between breeding grounds and the sea. One part of this question can be answered with some very interesting recent research. They have special adaptations to stay warm and to keep their eggs and chicks warm.

Gulls in Larnaca, taken 22/02/2010 by ©Stavros Christodoulides Recognizing that gull identification is confusing doesn’t help your average birdwatcher however. It is also familiar at inland sites in winter, especially reservoirs and refuse tips, and breeds in the relatively-Northerly regions of Europe, Asia, and North America.

Others, like the petrels and some of the auks, will lay a single egg per breeding attempt. The investment placed in each clutch bur seabirds is so great that only one breeding attempt can be seen to completion each year. They are cavity nesters, breeding in natural cavities or holes dug into the soil. So why do it?

Currently endemic to a single valley system in the Andes of Ecuador, this species escaped detection from researchers for thirty years until the rediscovery of a few pairs in November 1998 by Dr. Neils Krabbe. In November 2010, I backpacked for fifty days via the reasonably good bus system in Ecuador.
