(Brazilian Journal of Animal Science, 2023)
Description of the Nest and Eggs of the Great-billed Seed-Finch (Sporophila maximiliani)
(Wilson Ornithological Soc, 2016-09-01)
Seed-finches are Neotropical passerines highly specialized in the consumption of grass seeds. Most species are endangered because of the conversion of native grasslands into agricultural fields, and they are among the main ...
First description of the nest and eggs of the Sooty-faced Finch
(1994)
Sooty-faced Finches (Lysurus crassirostris) occur in dense undergrowth of wet forests that border streams along the Caribbean slope of Costa Rica between 600 to 1500 m in altitude. Its distribution is from Cordillera de ...
Egg production curve fitting using nonlinear models for selected and nonselected lines of White Leghorn hens
(Poultry Science Assoc Inc, 2012-11-01)
Egg production curves describe the laying patterns of hen populations over time. The objectives of this study were to fit the weekly egg production rate of selected and nonselected lines of a White Leghorn hen population, ...

Experimental evidence for an antipredatory function of egg rejection behaviour in a common host of the brood-parasitic shiny cowbird
(Springer, 2016-10)
Abstract: The rejection of foreign eggs is the most effective adaptation against brood parasitism in birds. Many hosts, however, show suboptimal responses towards parasitic eggs, which could reflect a compromise between ...
A giant soft-shelled egg from the Late Cretaceous of Antarctica
(Nature, 2020)
Egg size and structure reflect important constraints on the reproductive and life-history characteristics of vertebrates(1). More than two-thirds of all extant amniotes lay eggs(2). During the Mesozoic era (around 250 ...
