The nesting success of Gull-billed Terns was positively correlated with elevation and species richness of the nest site, and success of Black Skimmers was negatively correlated with species richness and positively correlated with elevation. [5] This species ranges from 212 to 447 g (7.5 to 15.8 oz), with males averaging about 349 g (12.3 oz), as compared to the smaller females 254 g (9.0 oz). RANGE: Oberholser, H. C. 1974.

PROTECTION / THREATS / STATUS: The reasons for the presumed declines in Texas are unknown. Flexible lower mandible is flattened and longer than the upper, about 1/3 more. Skimmers are locally common to uncommon on beaches, estuaries, bays, and lagoons; they occasionally appear inland in Texas on fresh water lakes and streams, mostly following tropical storms (Texas Ornithological Society 1995). Texas Colonial Waterbird Census Summaries, 1981-1992. Skimmers usually nest near the high tide mark, often resulting in inundation of nests by storm tides, excessive rain, or wave action (White et al. 0000030677 00000 n

Location of the nest in relation to vegetative cover, colony density and richness can strongly influence reproductive success via exposure to predators or weather events and competition for food resources and optimal nest sites. There must be other reasons for the gradual population decline in Texas. The North American Breeding Bird Survey Results and Analysis. Despite considerable heterogeneity among years, census summaries indicate that about 35% of the breeding population occurs on the upper coast, 16% on the central coast, and 49% on the lower coast (Texas Colonial Waterbird Society 1982, Texas Parks and Wildlife Dept. On the upper coast, they occasionally nest on pebbleor shell covered roof tops and parking lots (D. H. White, pers.

It is the unique bird having vertical pupil, allowing it to reduce them as a simple chap when in front of the sun, or to open as a circle with weak light. The black skimmer (Rynchops niger) is a tern-like seabird, one of three very similar birds species in the skimmer genus Rynchops in the gull family Laridae. 1984), and there was no evidence of mammalian or reptilian predators on the islands. Depue, J. They feed usually in large flocks, flying low over the water surface with the lower mandible skimming the water (in order of importance) for small fish, insects, crustaceans and molluscs[7] caught by touch by day or especially at night. Data from the Texas Colonial Waterbird Society (1982) also suggest that the breeding population of Black Skimmers in Texas is slowly declining.

Northern birds winter in Caribbean and South American birds make some short movements to feed. coverage both positively influenced the success of Least Terns. Black skimmer feeds mainly on small fishes, between 1, 20 to 4, 70 inches, and also crustaceans. The upper wings are black with white on the rear edge, and the tail and rump are dark grey with white edges. When it is threatened, it takes off, uttering harsh cries. 0000004023 00000 n
