1982). The species is currently very widespread and numerous in the Neotropics, extending its range south to Argentina. Checklist of the birds of Texas, 3rd ed.n. Completed nests averaged 57 cm (22 in) wide and 11 cm (4 in) deep. Sauer, J. R., J. E. Hines, G. Gough, I. Thomas, and B. G. Peterjohn. Although percentages vary among recent years, census summaries indicate that about 50% of the breeding population occurs on the upper coast, 31% on the central coast, and 19% on the lower coast (Texas Colonial Waterbird Society 1982, Texas Parks and Wildlife Dept. The roseate spoonbill is 71–86 cm (28–34 in) long, with a 120–133 cm (47–52 in) wingspan and a body mass of 1.2–1.8 kg (2.6–4.0 lb). Although Roseate Spoonbills probably never were extremely abundant in Texas, they were virtually extirpated there between 1850 and 1919 because of encroaching civilization and exploitation by the millinery trade (Allen 1942). The darker the shaded area, the more likely it is the bird species will find suitable climate conditions to survive there. Data from marked eggs in 29 nests confirmed that laying occurred at the rate of one egg every other day; the time in the nest until hatching is 23 days for the first egg and 22 days for the others (White et al. 1982. Texas Colonial Waterbird Society. DISTRIBUTION: The breeding range of the Roseate Spoonbill extends for over 800 km (500 mi) along the Texas coast, from the vicinity of Port Arthur in the north to that of Port Isabel in the south. This map depicts the range boundary, defined as the areas where the species is estimated to occur at a rate of 5% or more for at least one week within … Copyright © 2019 National Audubon Society, Inc. @media only screen and (max-width: 600px) { Since present numbers appear to be holding steady at about 2300 breeding pairs (Texas Parks and Wildlife Dept.

Phone: (979) 845-5777 When you sign the pledge, you will begin receiving communications from Audubon. The TBBAP findings confirmed breeding (76% of total nest records) in all of … Roseate spoonbills are plentiful in much of their range, but that hasn't always been the case. eBird data from 2014-2018. A unique education agency, the Texas A&M AgriLife Extension Service teaches Texans wherever they live, extending research-based knowledge to benefit their families and communities. The activities of the birds on the nest eventually formed a wide, shallow depression in which the eggs were laid. Upon this platform, live and dead stems of sea ox-eye (Borrichia frutescens), groundsel tree, and grasses were intertwined into a coarse lining about 5 cm (2 in) deep. Incubation begins the day after the first egg is laid, so the incubation period for each egg is 22 days. They are among the first to congregate at the colony sites, usually selecting nest sites in or atop low woody vegetation (rarely on the ground). 1992). /*-->*/. 2020. eBird Status and Trends, Data Version: 2018; Released: 2020. 2020. eBird Status and Trends, Data Version: 2018; Released: 2020. This map depicts the range boundary, defined as the areas where the species is estimated to occur at a rate of 5% or more for at least one week within the breeding season. The next three frames predict where this bird’s suitable climate may shift in the future—one frame each for 2020, 2050, and 2080. 1997, accessed on 7/13/98) show a slight increase (+1.5%) in spoonbill numbers for the entire Texas coast, but this trend may reflect normal population fluctuations. https://doi.org/10.2173/ebirdst.2018, Certain products may be unavailable due to insufficient data. . The colors indicate the season in which the bird may find suitable conditions— blue for winter, yellow for summer (breeding), and green for where they overlap (indicating their presence year-round).

Cornell Lab of Ornithology, Ithaca, New York. (1982) reported 150-200 nests on dredge-material islands in Nueces Bay at Corpus Christi during 1977-1980, and Oberholser (1974) referred to five large active colonies in the central coastal area in 1941 but did not mention nest estimates. This map depicts the range boundary, defined as the areas where the species is estimated to occur at a rate of 5% or more for at least one week within … Despite high levels of DDE in some Roseate Spoonbills at Nueces Bay, reproduction (fledglings/eggs laid) appeared to be good, averaging about 50% (White et al. University of Texas Press, Austin. No overlap means the species will leave its current range entirely. Spoonbills were intensely hunted for their beautiful feathers, used for ladies' hats, fans and screens. The most inland probable nest locale was Somerville Lake, quad C6 in latilong 30096. Roseate Spoonbill Platalea ajaja. Become an Audubon member today to help birds facing climate change. The nest base consisted of large dead twigs of groundsel tree (Baccharis halimifolia), border paloverde (Cercidium macrum), and Jerusalem-thorn (Parkinsonia aculeata) loosely fitted together to form a crude platform.

Texas A&M University With rosy pink wings, an orange tail, and a naked, blotchy, scaly grayish-green head, the Roseate Spoonbill is at once beautiful and bizarre. Dept..  1992.
