Jeffrey Spendelow, Ph.D.
Jeff Spendelow is an Scientist Emeritus at the Eastern Ecological Science Center in Laurel, MD
From 1982-1984 he worked as a Wildlife Biologist/Ecologist with the U.S. Fish and Wildlife Service’s (USFWS) National Coastal Ecosystems Team in Slidell, LA after receiving his Ph.D. (1980) and B.S. (1972) degrees in Biology from Yale University. In 2008 he was elected as a Fellow of the American Ornithologists’ Union, and he has been a Life Member of the AOU and several other ornithological societies since the 1970s. He has been the Director of PWRC’s Cooperative Roseate Tern Metapopulation Project (the CRTMP) ever since organizing it in 1987, and is the USGS member and Chair of the Technical Working Group of the USFWS’s Recovery Team for the endangered NW Atlantic breeding population of Roseate Terns.

A pair of roseate terns fledges three young with limited human assistance
Hays (1994) reported that a trio of Roseate Terns (Sterna dougallii) raised three fledglings in 1991 at Great Gull Island, New York. Despite the regular occurrence of "supernormal" clutches of three or more eggs (Norton 1988, Hays 1994, Shealer and Zurovchak 1995), we are not aware of any reports of three young being fledged by just two adult Roseate Terns. Here we report a pair that, with limitedAuthorsJeffrey A. Spendelow, James M. Zingo, Seah FossImpacts of trapping adult roseate terns on their reproductive success

Despite the death of her mate during the incubation period and a shortage (or lack of availability) of food in nearby waters, a female Roseate Tern (Sterna dougallii) nesting at the Falkner Island Unit of the Stewart B. McKinney National Wildlife Refuge in Connecticut was able to raise a chick to fledging in 1995 without human assistance. The growth and development of this chick was slower than tAuthorsJ. A.

Although Roseate Terns (Sterna dougallii) habituate to many research activities, the trapping and temporary removal of one of both members of a nesting pair may affect their annual and lifetime reproductive success. Protocols for trapping adult Roseate Terns that reduce the chances of nest desertion, neglect of chicks, and injury to adults were developed in the early 1980s, but both shortterm andAuthorsJames M.

Both members of seabird pairs are normally required to fledge young. Seabirds that nest in sites accessible to predators usually have one parent in attendance during the egg/chick phase. Time devoted to foraging can vary with individual skill and age, prey availability and abundance (Seamy 1978), and distance to foraging grounds (Safina 1990). Although average skill of similar-aged individuals sAuthorsJ. Burger, I.C.T. Nisbet, James M. Zingo, J. A. Spendelow, C. Safina, M. GochfeldVariations in growth of roseate tern chicks
We measured growth parameters of Roseate Tern (Sterna dougallii) chicks at two contrasting colonies: Bird Island, Massachusetts, and Falkner Island, Connecticut, from 1987 through 1990. Differences in growth parameters among individual chicks are used to explore differences in parental performance, whereas differences in average growth parameters among colonies and years are used to explore dAuthorsI.C.T.

Several multistratum capture—recapture models were used to test various hypotheses about possible geographic and temporal variation in survival, movement, and recapture/resighting probabilities of 2399 adult Roseate Terns (Sterna dougallii) color—banded from 1988 to 1992 at the sites of the four largest breeding colonies of this species in the northeastern USA.

A model-based analysis was done to test several hypotheses concerning the rates of loss of butt-ended color bands placed on adult Roseate Terns (Sterna dougallii) in the western North Atlantic. These birds were captured and color banded from 1987-1991 at four colony sites, and recaptured from 1989-1992 as part of a study of the population dynamics of this species.
