Cattle Egret (Bubulcus ibis) Science Article 6 abstract The first record of the Cattle Egret in Surinam on March 10, 1946 (Auk, 64: 143, 1947) proved of more importance than the mere observation of a straggler. In the same district I observed on December 12, 1946, two individuals on the bank of the Nickerie River. […]

Cattle Egret Bubulcus ibis habitat use andassociation with cattle
Cattle Egret (Bubulcus ibis) Science Article 5 abstract Cattle Egret Bubulcus ibis has a worldwide distribution. In India it is common in a variety of habitats, especially wetlands, throughout the peninsula. Freshwater marshes and paddy fields were identified as the most important foraging habitats by Meyerricks (1962) and Seedikkoya (2004), although there are pronounced seasonal […]
Naturally occurring secondary nutritional hyperparathyroidism in cattle egrets (bubulcus ibis) from central texas
Cattle Egret (Bubulcus ibis) Science Article 4 abstract Naturally occurring secondary nutritional hyperparathyroidism is described in the nestlings of two colonies of cattle egrets (Bubulcus ibis) from Central Texas (Bryan and San Antonio, Texas, USA). Nestlings from a third colony (Waco, Texas, USA) were collected in a subsequent year for comparison. Birds from the first […]
Notes on the foraging behavior of the Zigzag Heron.
Zigzag Heron (Zebrilus undulatus) Science Article 4 abstract The only recent field observations reported for the poorly known Zigzag Heron (Zebrilus undulutus) (Hancock and Kushlan, Herons Handbook, Croom Helm, London, 1984) are those of Davis et al. (Condor 82:460-46 1, 198 1). Here we report on a bird watched intermittently by NJCM for about 13 […]
Observations of the behavior of the zigzag heron
Zigzag Heron (Zebrilus undulatus) Science Article 5 abstract Reliable sight records of’the Zigzag Heron (Zebrilus undulatus) are said to be virtually nonexistent, and nothing has been recorded of the feeding, breeding or other habits of this species (Hancock and Elliot 1978). We therefore present our observations of an individual of this species and summarize several […]
The voice and first nesting records of the Zigzag Heron in Ecuador
Zigzag Heron (Zebrilus undulatus) Science Article 1 abstract Recent sightings of the little-known Zigzag Heron (Zebrilus undulutus) have come primarily from Peru, as reported by Mathews and Brooke (Wilson Bull., 100: 147-148, 1988) and by Davis et al. (Condor, 82:460-46 1, 1980). Neither Hilty and Brown (A Guide to the Birds of Colombia, Princeton Univ. […]
Phylogenetic relationships of the Zigzag Heron (Zebrilus undulatus) and white-crested Bittern (Tigriornis leucolophus) estimated by DNA-DNA hybridization
Zigzag Heron (Zebrilus undulatus) Science Article 2 abstract Recently we, acquired DNA of two rare species of heron, the Neotropical Zigzag Heron (Zebrilus undulatus) and the African White-crested Bittern (Tigriornis le colophus). To estimate their phylogenetic relationships to other herons, we compared these species with representatives of the major heron clades using DNA-DNA hybridization. Even […]
Prey Handling in Yellow-crowned Night Herons
Yellow-crowned Night Heron (Nyctanassa violacea) Science Article 1 abstract Although an extensive literature exists on the foraging ecology of wading birds (reviewed by Kushlan 1978), detailed studies of the Yellow-crowned Night Heron (Nyctanassa violacea) are lacking.The yellowcrown is unique among the ardeids in that it specializeson crustacean prey (Palmer 1962, Hancock and Elliott 1978) and […]
