Welcome to my cyber-résumé. 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.

ID Tips for Tricky Finches March 29, 2013 Ever been stumped by a streaky brown finch at your feeder? Or have trouble determining whether the "Purple" finch you're looking at is really a Purple Finch and not one of the other look-alike species? The trio of House Finch, Purple Finch, and Cassin's Finch provide one of the most challenging groups of birds to identify in North America. In some ways, immatures and females of all three species are more similar to each other than they are to adult males.

Birds With Child-care Assistance Invest Less In Eggs
Aug. 21, 2007 — 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.
Jan. 18, 2011 — 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.
