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.

Two hybrid common x roseate terns fledge at Falkner Island, Connecticut
Although these two similarly-sized species are sympatric throughout much of their breeding range, there are few published records of hybridization between Roseate (Sterna dougallii) and Common (S. hirundo) Terns. Records include at least five from Europe (Witherby and Ticehurst 1908, Perry 1972, Robbins 1974, Burggraeve 1977, van den Berg 1980) and only one from North America (Hays 1975), but we aAuthorsJames M.

From 1981-1990, 166 (10.1%) of 1636 Roseate Tern (Sterna dougallii) chicks banded from 1978-1985 at Falkner Island, Connecticut, [USA] and 68 (1.0%) of 6904 chicks banded during the same time period at all other colony sites in Connecticut, New York, and Massachusetts, were recaptured as breeding adults at Falkner Island. An analysis of the recapture data of the natal-site recruits resulted in anAuthorsJ. A. SpendelowCapture-recapture estimation of prebreeding survival rate for birds exhibiting delayed maturation
Many species of seabirds exhibit delayed maturity and do not return to the natal colony to breed for several years after fledging. Capture-recapture studies are frequently conducted at such breeding colonies and often include marking of young birds. However, because of the absence of these birds from the natal colony during the first few years after banding, the data do not fit neatly into existAuthorsJ. D. Nichols, J. A. Spendelow, J. E. HinesPatterns of species co-occurrence of nesting colonial Ciconiiformes in Atlantic coast estuarine areas
Patterns of co-occurrence of 11 species of nesting colonial Ciconiiformes in estuarine areas of the Atlantic coast from Maine to Florida were examined using Reciprocal Averaging and Detrended Correspondence Analyses. The first RA ordination axis categorized the species into two groups: species of large birds that often nest in the tops of large trees, and species of smaller birds that usually nesAuthorsJ. A. Spendelow, R.M. Erwin, B.K. WilliamsAnnual survival rates of breeding adult roseate terns
Analyses of the capture-recapture data on 910 individual Roseate Terns (Sterna dougallii) trapped from 1978-1987 as breeding adults on nests on Falkner Island, Connecticut, estimate the average annual minimum adult survival rate to be 0.74-0.75. There was weak evidence of year-to-year variation in annual survival rates during the study period. The Jolly-Seber models used to estimate survival ratesAuthorsJeffrey A. Spendelow, James D.

Using previously published atlas data for 122 mixed-species wading bird colonies on islands along the Atlantic coast (Maine to Florida, 1976-77), we examined relationships between population sizes of 11 species of egrets, herons, ibises, and wood storks (Mycteria americana) and nine habitat variables. On nautical charts, we measured four island characteristics (area, length, width, shape), three iAuthorsR.M. Erwin, J. A. Spendelow, P.H. Geissler, B.K. WilliamsRelationships between nesting populations of wading birds and wetland habitat features
We used data from censuses of wading bird colonies on the Atlantic coast from Maine to Florida {1976-1977) to examine relationships between population sizes of wading birds {herons, egrets, ibises) and 9 key habitat features. Variables included features of the colony site {island size, dimensions, isolation from adjacent land) and surrounding (5 km circle) potential feeding habitat {wetland area).AuthorsR.M. Erwin, J. A.
