This dataset comprises GPS location analyzed in Lamb et al. (2017): 165,562 deployed GPS locations, for 81 Eastern brown pelicans (25 in Florida, 27 in Louisiana, and 29 in Texas) tracked from 2013-04-24 to 2016-02-05. Funding for this study was provided by the Bureau of Ocean Energy Management and U.S. Geological Survey (Interagency Agreement no. M12PG00014). The Eastern Brown Pelican (Pelecanus occidentalis carolinensis) is a large-bodied seabird that nests in colonies of 10 to upwards of 5,000 pairs, on nearshore barrier islands in subtropical and tropical North American waters. It breeds between March and August, laying 2–3 eggs and raising 1–2 chicks per year. The species is facultatively migratory during...
Distribution, movements, and habitat use of 10 wild adult razorback suckers (Xyrauchen texanus) were examined in Lake Mohave, Arizona-Nevada, from November 1994 through July 1997. Movement rates (0.00?17.35 km d?1) and ranges (x?= 39 km) were similar to those for riverine populations. All study fish returned to spawning sites used in previous years, but they also visited other spawning areas. Spawning females were significantly (P = 0.031) more active than males (480 vs. 87 m d?1) and moved substantial distances between spawning sites during peak reproduction (1?28 February). Fish became most active (m d?1, km month?1) after spawning and moved to areas known to support higher algal production. Fish were typically...

Trout Unlimited will extend its existing Adopt-a-Trout program to the Henrys Fork River, a tributary to the Green River in the Colorado River basin. The project will include work with the Wyoming Game and Fish Department and local schools to tag and monitor Colorado River Cutthroat trout movements to learn more about fish passage issues, areas of high entrainment, habitat use, and native and wild trout migratory patterns. Colorado River Cutthroat trout are native to the Henrys Fork River and occupy portions of the drainage; however, no data exists for Colorado River Cutthroat trout in the Wyoming portion of the Henrys Fork drainage to understand population dynamics and habitat restraints.FY2014Trout Unlimited will...

Nine Heloderma suspectum were observed between 1 April and 13 July 1979. In April and May, movements of Heloderma were associated with areas where eggs of ground nesting birds were most abundant. During June and July, Heloderma responded to decreasing egg availability by shifting their diets to small mammals and moving onto areas where these prey were most abundant. These shifts are adaptive as Heloderma continually exploit the most abundant prey. Lizards demonstrated a foraging strategy of rarely backtracking and consuming only an average of 46% of the eggs available at each nest. The number of eggs eaten per day by each lizard was positively correlated with lizard weight. Combinations of lizard satiation, reproduction,...
We used radio-telemetry to study the movements and habitat use of Western toads (Bufo boreas) in the Targhee National Forest in southeastern Idaho. Eighteen toads (10 male and 8 female) that bred in a seasonally flooded pond, were fitted with radio-transmitters, tracked, and their movements mapped and analyzed with global positioning and geographic information systems. We also analyzed their patterns of habitat selection at micro- and macro-scales by comparing sites used by toads with randomly selected sites. After breeding, two male and six female toads left the breeding pond and used terrestrial habitats extensively. Male and female toads showed different patterns of movement and habitat use, although all toads...

This dataset comprises reference data for each individual bird included in Lamb et al. (2017). Reference data include, but are not limited to, colony name, nest coordinates, nest content, culmen size, tag manufacturer, etc. Funding for this study was provided by the Bureau of Ocean Energy Management and U.S. Geological Survey (Interagency Agreement no. M12PG00014). The Eastern Brown Pelican (Pelecanus occidentalis carolinensis) is a large-bodied seabird that nests in colonies of 10 to upwards of 5,000 pairs, on nearshore barrier islands in subtropical and tropical North American waters.

Funding for this study was provided by the Bureau of Ocean Energy Management and U.S. Geological Survey (Interagency Agreement no. M12PG00014). This study focuses on obtaining information about populations of Brown Pelican (Pelecanus occidentalis carolinensis) across the northern Gulf of Mexico. Study objectives are to (1) document dispersal, seasonal and annual movements, seasonal home range, and site fidelity of marked adult Brown Pelicans among nesting colonies from the Gulf coast, (2) compare contaminant exposure risk, contaminant levels, and health parameters in adult and nestling Brown Pelicans from various colony sites, and (3) document the relationship of local environmental, nest site characteristics and...
