Browse around to find out about my research and publications on birds of prey, birds of the New World Tropics, habitat fragmentation in the Amazon, ecology, and conservation, as well as my graduate students, courses taught (ornithology and sometimes field ecology), and links to interesting pages on the Web, including a number of local conservation organizations with which I'm involved. Ospreys: I've been studying the Osprey population on Martha's Vineyard, MA, since 1969.
Beginning in 2000, in collaboration with Dr. Mark Martell of The Raptor Center at the University of Minnesota, I put satellite transmitters on a total of seven adult birds, six on Martha's Vineyard and one in Charlotte. Bird identification guide. News and Features — eBird. New Big Day route for Team Sapsucker The annual Big Day fundraiser is hugely important to eBird and the Cornell Lab of Ornithology.
For the past three years Team Sapsucker has visited Texas to chase the North American Big Day record. We were thrilled to break (and then tie) the record with 264 species in each of the first two years and a mind-blowing 294 in 2014, on a perfect run in a perfect year. We honestly don’t believe we can do any better in Texas, so instead we decided to focus this year’s Big Day on the one other area we think might give Texas a run-for-its-money.
Most Big Days in North America make one assumption that we plan to challenge this year–see if you can figure out what it is! Birds With Child-care Assistance Invest Less In Eggs. An Australian bird has been found to produce smaller, less nourishing eggs when it breeds in the presence of other 'helper' birds that provide child-care assistance.
This unique adaptation enables the birds to live longer and breed more often than females without helpers. The research, led by a University of Cambridge academic, was published in Science. In many animal species, parents caring for their offspring are assisted by so-called 'helpers', adults that forego reproduction to help others raise young. Although parents decrease the amount of food they provide to offspring when helpers are present, the additional supply provided by the helpers more than compensates for this reduction. Australian birds attract mates with 'scary movie effect' Using a horror film to bring your date closer is a classic move in the teenage playbook.
Now, a study of Australian birds finds that other animals use the same "scary movie effect" to attract female attention, by hitchhiking mating signals onto the calls of predators. Male splendid fairy-wrens, a sexually promiscuous small bird native to Australia, are known to sing a special song each time they hear the call of one of their predators, the butcherbirds.
