The first shorebird arrivals are apparently birds that failed at a breeding attempt and don’t have time to re-attempt; they might as well head south early. By checking my Facebook feed on a daily basis, I had a broad idea about birds arriving into different countries in Central and SouthAmerica.
I would never have believed it, but if the science says so who am I to argue otherwise?

Males of this species are more brightly colored in their non-breeding winter plumage. In 1996, several pipit specimens were collected for DNA analysis and it turned out that there was not one, but two new species to science in this sample! A dancing Blue Crane , South Africa’s national bird.
Erika is a first year graduate student studying Ecosystem Science and Conservation at Duke. The park is home to not one, not two, but large three colonies of breeding seabirds: the Brown Noddy , Magnificent Frigatebird , and Sooty Tern. Lots and lots of birds. It was for the birds that we made this journey in the first place.
49-50) She is also adept at writing about conservation’s larger context in terms of its history, public policy struggles, and the science behind species re-introduction. Well-researched and footnoted, these sections never feel disconnected from the more personal sections.
A new study published in The Condor analyzed the feathers of Bobolinks to determine what they eat after they leave their North American breeding grounds and fly south for the winter.
