Abstract Marcot, Bruce G. 1995. Owls of old forests of the world. Gen. Tech. Rep. PNW- GTR-343. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 64 p. A review of literature on habitat associations of owls of the world revealed that about 83 species of owls among 18 genera are known or suspected to be closely asso- ciated with old forests. Old forest is defined as old-growth or undisturbed forests, typically with dense canopies. The 83 owl species include 70 tropical and 13 tem- perate forms. Specific habitat associations have been studied for only 12 species (7 tropical and 5 temperate), whereas about 71 species (63 tropical and 8 temperate) remain mostly unstudied. Some 26 species (31 percent of all owls known or sus- pected to be associated with old forests in the tropics) are entirely or mostly restricted to tropical islands. Threats to old-forest owls, particularly the island forms, include conversion of old upland forests, use of pesticides, loss of riparian gallery forests, and loss of trees with cavities for nests or roosts. Conservation of old-forest owls should include (1) studies and inventories of habitat associations, particularly for little-studied tropical and insular species; (2) protection of specific, existing temperate and tropical old-forest tracts; and (3) studies to determine if reforestation and vege- tation manipulation can restore or maintain habitat conditions. An appendix describes vocalizations of all species of Strix and the related genus Ciccaba. Keywords: Owls, old growth, old-growth forest, late-successional forests, spotted owl, owl calls, owl conservation, tropical forests, literature review. -
Wood Warblers Wintering in Cuba
WOOD WARBLERS YINTERING IN CUBA BY STEPHEN W. EATON ITTLE is known concerning the winter behavior of the various species of L North American wood warblers (Parulidae) which retire south of the United States in the fall. Are they sedentary or do they wander over broad geographic areas? What degree of sociality among individuals and species is present? Because of the abundance of warblers in Cuba during the winter this island is an ideal place to study these questions. From December 23, 1948 to January 3, 1949 I was on the island of Cuba with Ernest P. Edwards and George E. Grube. We stayed at the Harvard University Tropical Station which is approximately ten kilometers northeast of Cienfuegos. Habitats typical of this locality were well described by Barbour (1922:16-17). Much of the land in this area has been cleared of its native vegetation to make way for sugar cane and pasture. The areas still forested are located on limestone outcrops, alon g fresh and brackish water streams, and along fence rows. Because of the abundance of termites, fences are of live trees, principal- ly Bursura sp. and Gliricidia sp. The winter fruits of these trees and their insect fauna attract many birds. My primary objective was to study the winter habits of the Ovenbird (Seiurus aurocapiZZus), Northern Water-thrush (Seiurus noveboracensis), and Louisiana Water-thrush (Se&us motacilla) . Three areas of habitat typical for these birds were chosen for study. The Ovenbird was found in upland woods; the Northern Water-thrush in and adjacent to mangroves; and the Louisiana Water-thrush along wooded fresh-water streams. -
21 Sep 2018 Lists of Victims and Hosts of the Parasitic
version: 21 Sep 2018 Lists of victims and hosts of the parasitic cowbirds (Molothrus). Peter E. Lowther, Field Museum Brood parasitism is an awkward term to describe an interaction between two species in which, as in predator-prey relationships, one species gains at the expense of the other. Brood parasites "prey" upon parental care. Victimized species usually have reduced breeding success, partly because of the additional cost of caring for alien eggs and young, and partly because of the behavior of brood parasites (both adults and young) which may directly and adversely affect the survival of the victim's own eggs or young. About 1% of all bird species, among 7 families, are brood parasites. The 5 species of brood parasitic “cowbirds” are currently all treated as members of the genus Molothrus. Host selection is an active process. Not all species co-occurring with brood parasites are equally likely to be selected nor are they of equal quality as hosts. Rather, to varying degrees, brood parasites are specialized for certain categories of hosts. Brood parasites may rely on a single host species to rear their young or may distribute their eggs among many species, seemingly without regard to any characteristics of potential hosts. Lists of species are not the best means to describe interactions between a brood parasitic species and its hosts. Such lists do not necessarily reflect the taxonomy used by the brood parasites themselves nor do they accurately reflect the complex interactions within bird communities (see Ortega 1998: 183-184). Host lists do, however, offer some insight into the process of host selection and do emphasize the wide variety of features than can impact on host selection. -

Distribution, Ecology, and Life History of the Pearly-Eyed Thrasher (Margarops Fuscatus)
Adaptations of An Avian Supertramp: Distribution, Ecology, and Life History of the Pearly-Eyed Thrasher (Margarops fuscatus) Chapter 6: Survival and Dispersal The pearly-eyed thrasher has a wide geographical distribution, obtains regional and local abundance, and undergoes morphological plasticity on islands, especially at different elevations. It readily adapts to diverse habitats in noncompetitive situations. Its status as an avian supertramp becomes even more evident when one considers its proficiency in dispersing to and colonizing small, often sparsely The pearly-eye is a inhabited islands and disturbed habitats. long-lived species, Although rare in nature, an additional attribute of a supertramp would be a even for a tropical protracted lifetime once colonists become established. The pearly-eye possesses passerine. such an attribute. It is a long-lived species, even for a tropical passerine. This chapter treats adult thrasher survival, longevity, short- and long-range natal dispersal of the young, including the intrinsic and extrinsic characteristics of natal dispersers, and a comparison of the field techniques used in monitoring the spatiotemporal aspects of dispersal, e.g., observations, biotelemetry, and banding. Rounding out the chapter are some of the inherent and ecological factors influencing immature thrashers’ survival and dispersal, e.g., preferred habitat, diet, season, ectoparasites, and the effects of two major hurricanes, which resulted in food shortages following both disturbances. Annual Survival Rates (Rain-Forest Population) In the early 1990s, the tenet that tropical birds survive much longer than their north temperate counterparts, many of which are migratory, came into question (Karr et al. 1990). Whether or not the dogma can survive, however, awaits further empirical evidence from additional studies. -

The form that occurs in the NACC area is nominate pacificus, so the current species account would remain unchanged except for the distributional statement and notes. Background: The Fork-tailed Swift Apus pacificus was until recently (e.g., Chantler 1999, 2000) considered to consist of four subspecies: pacificus, kanoi, cooki, and leuconyx. Nominate pacificus is highly migratory, breeding from Siberia south to northern China and Japan, and wintering in Australia, Indonesia, and Malaysia. The other subspecies are either residents or short distance migrants: kanoi, which breeds from Taiwan west to SE Tibet and appears to winter as far south as southeast Asia. -

The Birds of Long Island, Bahamas
Wilson Bull., 104(2), 1992, pp. 220-243 THE BIRDS OF LONG ISLAND, BAHAMAS DONALD W. BUDEN ’ ABSTRACT.-ChIe hundred and ten species of birds are recorded from Long Island and adjacent cays, 54 for the first time. No species or subspecies is endemic. Of the 48 probable breeding indigenous species, 23 are land birds, most of which are widely distributed in all terrestrial habitats. The Yellow Warbler (Dendroicapetechia) shows the strongest habitat preference, being nearly confined to mangroves. Nests, eggs, and young are reported for 3 1 species, 19 of them for the first time on Long Island. The White-winged Dove (Zenaidu asiatica) and Blue-gray Gnatcatcher (Polioptila caerulea) are new additions to the list of breeding land birds. The Bahama Mockingbird (Mimus gundluchii)was the most frequently encountered bird during summer 1990, followed closely by the Thick-billed Vireo (Vireo crassirostris).Received I6 May 1991, accepted5 Nov. 1991. The avifauna of Long Island has never been reviewed systematically, the literature consisting mainly of brief and sparsely annotated noncu- mulative lists of species. In nearly all cases, these earlier reports have been based on visits of only one to several days duration covering a very limited area, mainly Clarence Town and vicinity. The present report brings together all available information on the distribution of the birds of Long Island and is based in large measure on my observations through- out the island during 28 April-l 3 May and 6 July-l 2 August 1990 together with unpublished records contributed by other observers. STUDY AREA Long Island is located in the central part of the Bahama archipelago and is the south- easternmost island of any appreciable size on the Great Bahama Bank (Figs. -

Bahama Mockingbird Mimus gundlachii The Bahama Mockingbird breeds throughout the Bahama Islands south to the Turks Bank north of Hispaniola, o cays along the northern coast of Cuba, and curiously, in an isolated region of dry limestone forest along the southern Jamaican coast. In the late nineteenth century, it was virtually unknown on the most northerly Bahamian islands, but it is now well established on Abaco and apparently on eastern Grand Bahama. In Florida, the Bahama Mockingbird is rare but regular along the southeast coast and Keys since 1987 (Stevenson and Anderson 1994). Habitat. Until recently, the biology of the Bahama Mockingbird was completely unknown. In the Bahamas and Greater Antilles, the Bahama Mockingbird prefers dry scrub habitats. Nests found in Florida in May and June resembled Northern Mockingbird's. Statements in some older literature noting that the "more aggressive" Northern Mockingbird was driving it into oblivion are completely unsubstantiated. The more thrasher-like Bahama Mockingbird is less associated with human disturbance than the Northern Mockingbird and is generally far less demonstrative over most of the yea Development of the more populated Bahamian Islands has simply had the effect of substituting an obvious, exuberant species for one relatively shy around man.
