The development and stability of filial preferences in the chick (Gallus gallus)

The development and stability of filial preferences was investigated in domestic chicks (Gallus gallus). It is know that soon after hatching, precocial birds (such as chicks) rapidly form a social preference for the first conspicuous object to which they are exposed, a phenomenon known as 'imprinting'. In the natural situation this will be the mother (and siblings). It has been shown, however, that chicks can become 'imprinted' on a whole range of artificial mother-surrogates.
