Abstract By combining all available banding and tracking data, we found that Willets (Tringa semipalmata) have a strong migratory connectivity between breeding nonbreeding locations at the range-wide subspecies levels, exposing two to varying threats such as hunting for eastern semipalmata climatically-altered coastal habitats both subspecies. We western inornata) primarily used along Pacific Coast of United States, although their reported range extends US Atlantic Gulf Coasts Central South...
The federally Threatened Eastern Black Rail (Laterallus jamaicensis jamaicensis) is difficult to detect and may not be well monitored by existing survey methods. goals of this project were explore occupancy detectability Rails along the Texas Gulf Coast determine best months time day conduct surveys. We conducted surveys at 90 points in San Bernard NWR Brazoria from 5 March through 31 May 2014. visited each point six times—twice dawn, dusk, night used playback elicit vocalizations. measured...
Numbers, densities, and sex ratios of Yellow Rails (Coturnicops noveboracensis) wintering at Red Slough Wildlife Management Area in McCurtain County, Oklahoma, USA, were approximated compared to estimates from birds coastal Texas, USA.

Habitat use by the Eastern Black Rail (Laterallus jamaicensis jamaicensis) in coastal Texas, USA is poorly understood. To provide data for effective management of subspecies home range size was estimated and habitat examined. From February-May 2017 2018, regular locations 13 radio-transmitted Rails were obtained at San Bernard National Wildlife Refuge, Texas.

Yellow Rail (Coturnicops noveboracensis) is a species of conservation concern, while the Eastern Black (Laterallus jamaicensis jamaicensis) has recently been listed as Threatened.

During the last 2 centuries, widespread declines have been observed in migratory species, and these largely linked to anthropogenic causes. Migrants move across multiple spatiotemporal scales with wide-ranging movements that can cross jurisdictions. Consequently, conservation management require incorporation of movements. However, for many nongame basic information on migration wintering ecology is poorly known. Yellow Rails (Coturnicops noveboracensis), LeConte's Sparrows (Ammospiza...
Abstract Yellow rails ( Coturnicops noveboracensis ) are secretive, nocturnal marsh birds that challenging to survey. During the breeding season, males will respond click‐click vocalization call playbacks and can also be detected using autonomous recording units (ARUs). occasionally vocalize during spring migration but seldom, if ever, use this autumn winter. Consequently, detections of yellow have relied on effort‐intensive approaches such as draglines or serendipitous encounters. On 28...

Herein we provide direct evidence for the consumption of Pomacea maculata (Giant Applesnail) eggs by ants in genus Crematogaster. The observations were made during removal snail egg masses at Hudson Woods Unit Texas Mid-Coast National Wildlife Refuge, TX. We observed acrobat (Crematogaster sp.) removing from an mass and carrying back to their nest. While predation on applesnail has been reported elsewhere, our knowledge this is first time that it North America.
Knowledge of the geographic linking individuals or populations between different annual life cycle stages is essential for effective conservation decision making. The Willet (Tringa semipalmata) composed two distinct subspecies that are separated by breeding habitat in North America, with eastern Willets estuarine marshes along Atlantic and Gulf Coasts western wet grasslands prairies interior west America. We studied migratory paths wintering locations Texas Coast from 2015 to 2019 using...
