Data were collected from the North American Breeding Bird Survey and the Pan-European Common Birds Monitoring Scheme. The total overall impact on bird populations, related to climate change, is the same in North America (on the right) and Europe (on the left). Again, Europe is on the left, North America is on the right.

The source of this ranking, BirdLife International, lists Bolivia as currently having 1,439 bird species, including 18 breeding endemics. This is more than eBird reports–a checklist generated from the citizen science database lists only 1,413 species. Clearly, this is an under-birded country. . More on Species Accounts.

For those who didn't read the five-part Slate series " Pepper, the stolen dog who changed American science " by Daniel Engber , I recommend it for the history, but also for the misconceptions and assumptions that you might want to discuss on the Facebook discussion about the series.

The second thing to note is that this is an excellent and courageous book that tackles a group of birds whose field identification has stumped the most skilled birders. The book expands field guide boundaries with its narrow focus on two genera (groups) with a bonus Tufted Flycatcher thrown in for good measure.

And much of that time is spend loafing around the breeding colonies trying to pair off and engaging in silly-looking behaviours referred to as dancing by scientists. It can take over a year to raise a chick for the larger species, and even species that can fit their entire breeding cycle into one year tend not to breed in consecutive years.

DNA evidence then indicated that they are an ancient group mostly closely related to the bizarre and wildly different rockfowls and they were therefore contentiously placed in the Picathartes family, before finally finding a contented home in their own family, Chaetopidae.

Consider their plumage, waterproof and dense like all aquatic birds, but each feather attached to their skin at a right angle with a curl to the tip which traps air against the body. I would never have believed it, but if the science says so who am I to argue otherwise? But that’s a group for a different time.

The consultant also suggested increasing readership by catering to highly specific niche interest groups. eBird states that “small white patch on throat is not obvious and difficult to see” And they use a photo that I submitted as main illustration, so they must be right.

Nonprofit organizations, science, and the best intentions in the world came to the rescue with a captive breeding program, and we now have over 400 Pink Pigeons living in Mauritius, the nearby island of Ile aux Aigrettes, and the zoos hosting the breeding program, including the Bronx Zoo.

They reach breeding maturity at four to seven years of age, produce only one chick per nesting season, and only one in three offspring survive to fledging age. Ohio has tracked two families of their state-endangered breeding sandhill cranes and found them to have wintered over in Tennessee in 2010. Isn’t that neat?

All of this leads to a longer life list, which is, after all, the entire point of bridwatching, right? If migration evolved many times in birds, then it would be worth asking if it evolved in birds more often than in other groups of vertebrates. Well, you know I’m only joking about the life list. Consider the implications.

Hopefully, the winter time in Shanghai gives the Black-faced Buntings some time to relax from the challenges of the breeding season. One Japanese study found that it arrives at its breeding grounds earlier than in the past, most likely due to increased spring temperatures. No wonder no species are named after me.
