Behaviour of the cattle egret Ardeola ibis
… work was extended to include two other species, Egretta garzetta and E. intermedia. The present study is also designed to provide material for a projected review of the Ardeidae (Curry-Lindahl pers. comm.).

An Examination of Gene Flow Among Distinct Management Units of The Reddish Egret
The Reddish Egret (Egretta rufescens) is one of the least studied herons in North America. It ranges from Baja California to the Bahamas, north to Texas and Louisiana and southwards to Central America and the northern part of South America. I examined gene flow and genetic diversity among …

Molecular Genetic Assessment of Population Structure, Paternity, and Sex Ratios for the Reddish Egret
… examined distantly isolated colonies of Reddish Egret to determine global population genetic structure. We analyzed 13 polymorphic satellites and used nine of them to accomplish seven goals: 1) to assess range wide population differentiation among Reddish Egret (Egretta rufescens) populations, 2) …

Wintering Reddish Egret (Egretta Rufescens) Foraging Response To Environmental Variability On The Southern Texas Gulf Coast
The Reddish Egret (Egretta rufescens) is a rare species of heron due to its limited geographic range as well as its narrow habitat requirement, relying exclusively on coastal tidal flats throughout its yearly cycle. It is therefore vulnerable to stressors ranging from human coastal development to …

ΒΙΟΛΟΓΙΑ ΚΑΙ ΟΙΚΟΛΟΓΙΚΗ ΣΥΜΠΕΡΙΦΟΡΑ ΤΟΥ ΛΕΥΚΟΤΣΙΚΝΙΑ (EGRETTA GARZETTA) ΣΤΗΝ ΤΕΧΝΗΤΗ ΛΙΜΝΗ ΚΕΡΚΙΝΗΣ ΣΕΡΡΩΝ
… THE BREEDING AND FORAGING BIOLOGY OF THE LITTLE EGRET (EGRETTA GARZETTA) WAS STUDIED AS WELL AS THE BEHAVIORAL ECOLOGY OF THE ABOVE SPECIES ACCORDING TO THE SEASONAL FLUCTUATION OF THE WATER LEVEL DURING THE CRUCIALTIME OF BREEDING. THE SEASONAL FLUCTUATION OF THE WATER LEVEL THE LAKE, AFFECTS …

Foraging Behavior and Success of Herons and Egrets in Natural and Artificial Wetlands
… I quantified the foraging behavior of herons and egrets (species that are dependent on wetlands for food) in natural and artificial wetlands in southeastern coastal Georgia and southern coastal South Carolina. I tested the hypothesis that wading birds would show similar foraging behavior and …

Reproductive Peformance of Great Egrets (Ardea alba) at High Island, Texas
… no significant inter-annual variation in Great Egret reproductive performance. I examined the reproductive performance of Great Egrets (Ardea alba) for two breeding seasons (2009 and 2010) immediately following Hurricane Ike at High Island, Texas. Breeding success, productivity, and mean brood …

Sedimentological lithofacies, internal architecture and evolution of deep marine fans of the Tithonian Angel Formation, Northwestern Dampier Sub-basin, North West Shelf, Australia.
… Terrace, which contains the Mutineer, Lambert, Egret and Montague fields, contains a seventh order system that comprises curved, coalescing fan systems up to 15 kilometres long separated by up to six lowstand events. The central Dampier Sub-basin, which contains the Angel, Cossack and Wanaea …

Solar flare gamma-ray spectroscopy with CGRO-COMPTEL
… analyses of this flare using COMPTEL, OSSE and EGRET data yielded a hard proton spectrum with a power law index around 2 using the 2.2 to 4.44 MeV fluence ratio. This hard of a spectrum would indicate the presence of a high-energy component above eight MeV and emission due to spallation …
