We demonstrate a novel mechanism for prey detection in birds. Red knots (Calidris canutus), sandpipers that occur worldwide in coastal intertidal areas, are able to detect their favourite hard-shelled prey even when buried in sand beyond the reach of

Stereotypy of pecking in chickens as a result of similar sensory input, was analysed by employing the Coefficients of Variation and Concordance. Movements of head, beak and tongue, filmed with a high speed camera, and the beak's gape recorded with a

We propose a model of filter feeding in Caribbean (Phoenicopterus r. ruber) and Greater Flamingos (P. r. roseus) that is based on a description of the oropharyngeal integument, using SEM and radiography, and analysis of kinematics and performances. O

This study presents a cinefluoroscopic and electromyographic analysis of the feeding behavior of squab during regurgitation feeding. Two phases are distinguished in this behavior: the gaping phase, in which the squab holds its beak wide open while th

The structure of the syrinx of male adult and juvenile Collared doves (Streptopelia decaocto) was examined on macroscopical, light- and scanning electron microscopical level to further knowledge of its functioning. Several syringeal structures were m

The mechanics of the skull of the pigeon are analyzed quantitatively, based on a three-dimensional kinematic computer model that considers the skull as a mechanism (Goodman, '60). The degrees of freedom at each cranial joint are defined and translate

Ingestion of food and water in birds is mediated by an extremely diverse trophic system which traces back upon only two modifications of one single anatomical design, i.e. a kinetic, beaked skull. The mechanics of ingestion are characterized by lower

An overwhelming range of special foraging and feeding techniques have evolved in birds. Generally, these adaptations are reflected in the external anatomy of the bill, their main manipulative tool. Such adaptations can also be seen in certain inner o
