CHEMICAL ATTRACTION OF NEWLY HATCHED OYSTER DRILLS

Energy utilization in newly hatched chicks.

The changes in body weight and composition were examined in broilers that either had immediate access to feed and water or had not been fed for 48 h posthatch. Chicks without access to feed decreased in BW by 7.8% in the 48 h posthatch, which was equivalent to 5.3 kcal/45 g chick/d. However, during this period the small intestines increased in weight and protein content by 80% or more. The decr...

Thermoregulation in Newly Hatched Black-legged Kittiwakes

The development of gull chicks is typically considered semi-precocial, because the birds remain in or near the nest for some days after hatching and depend on parental care, but hatch with downy coverings and possess some thermoregulatory ability (Drent 1967; Palokangas and Hissa 1971; Dawson et al. 1972, 1976; Dunn 1976; Dawson and Bennett 1980. 1981). Newlv hatched chicks of several gull spec...

Unsupervised statistical learning in newly hatched chicks

The ability to extract probabilistic information from visual inputs has been reported in human adults and infants (reviewed in [1,2]), and in adults of non-human species, though only under supervised (conditioning) procedures [3]. Here, we report spontaneous sensitivity to the probabilistic structure underlying sequences of visual stimuli in newly hatched domestic chicks using filial imprinting...

Newly hatched chicks solve the visual binding problem.

For an organism to perceive coherent and unified objects, its visual system must bind color and shape features into integrated color-shape representations in memory. However, the origins of this ability have not yet been established. To examine whether newborns can build an integrated representation of the first object they see, I raised newly hatched chicks (Gallus gallus) in controlled-rearin...
