Fish and Wildlife Service has listed the “Rufa” population of Red Knot ( Calidris canutus rufa ) as a threatened species under the Endangered Species Act (ESA). The other sub-species, Calidris canutus roselaari , migrates along the Pacific Coast and breeds in Alaska and the Wrangel Island in Russia. Conservation'

Detailed range maps with a textual range description for each species are included. Philippe J.

I find the information helpful and insightful, as it can shed light on why some species were or were not seen on that trip.

He also believes that we are living in an era of incredible scientific research, one in which new genetic technology and findings from diverse scientific disciplines have turned assumptions upside down, opened up new lines of thought, and provided answers, or at least probable answers, to many of our questions about why birds do the things they do.

Rice farmers may use pesticides, or other methods to prevent the birds from eating their crops, further hastening the decline of the species. Bobolink photo courtesy of R.M.

An associated issue is that the Belize and Costa Rica guides share many of the same descriptions of species, written by Howell. Similarly, descriptions of species repeated across volumes do not lose their accuracy with each publication. Other species are splits and lumped and have had their names changed. Why are these issues?

Its species name graydoni is in honor of Philip Newenham Graydon (1864-1940), a British planter in Sabah. Why that makes Mr. Graydon worthy of having a bird species named after him is a mystery to me.
