TOPOGRAPHY and MORPHOLOGY of RETINAL GANGLION-CELLS in FALCONIFORMS - A STUDY ON PREDATORY and CARRION-EATING BIRDS
(Wiley-Blackwell, 1991-02-01)
The topographic distribution of retinal ganglion cells and their cell body size have been studied in five Falconiform species, including predatory (chilean eagle Buteo fuscenses australis, and sparrow hawk Falco sparverius) ...

Trophic ecology of the Ringed Warbling-Finch (Poospiza torquata) in Neotropical semi-arid scrublands
(Csiro Publishing, 2014-03)
Seed-eating birds in temperate deserts must cope with great variation in the availability of their food resources. We studied the trophic ecology of Ringed Warbling-Finches (Poospiza torquata) in semi-arid scrublands of ...
Influence of Dietary Lysine Levels and Arginine:Lysine Ratios on Performance of Broilers Exposed to Heat or Cold Stress during the Period of Three to Six Weeks of Age
(1997-03-01)
Four trials of identical experimental design were conducted to determine the effects of temperature, dietary Lys level, and dietary Arg:Lys ratios on performance and carcass yield of male broilers. Birds of a commercial ...

Dietary modulation of intestinal enzymes of the house sparrow (Passer domesticus): Testing an adaptive hypothesis
(Elsevier Science Inc., 2000-01)
Insectivorous/frugivorous passerine species studied so far lack the ability to modulate intestinal maltase activity, in contrast to galliformes. We tested for dietary modulation of small intestine (SI) enzymes including ...
On the intraspecific variability in basal metabolism and the food habit hypothesis in birds
(2010)
The food habits hypothesis (FHH) stands as one of the most striking and often-cited interspecific patterns to emerge from comparative studies of endothermic energetics. The FHH identifies three components of diet that ...

The Role of Stubble Type and Spilled Seed Biomass on the Abundance of Seed-Eating Birds in AgroecosystemsEl rol del tipo de rastrojo y la biomasa de semillas derramadas sobre la abundancia de aves que se alimentan de semillas en agroecosistemas
(Sociedad Española de Ornitología, 2017-01)
Las tierras de cultivo son hábitats con alta disponibilidad de recursos para las aves granívoras. El uso de un determinado campo por las aves puede variar considerablemente dependiendo de la identidad del cultivo. Ciertos ...
