A reversed Ebbinghaus–Titchener illusion in bantams (Gallus gallus domesticus)
Animal Cognition, 2013A disk surrounded by smaller disks looks larger, and one surrounded by larger disks looks smaller than reality. This visual illusion, called the Ebbinghaus-Titchener illusion, remains one of the strongest and most robust illusions induced by contrast with the surrounding stimuli in humans.

Discrimination between individual humans by domestic fowl ( Gallus gallus domesticus )
British Poultry Science, 20011. We demonstrate that Barred-Rock and Isa-Brown hens can discriminate between the presence of 2 different humans and use this information as a cue for whether or not to make an operant response. 2. This demonstration in domestic fowl, the first of its kind in any avian subject, is consistent with a growing body of evidence that many species, including

Tavuklarda (Gallus Gallus Var. Domesticus)Megabakteriyel Proventriculitis
1997In this pa per, megabacterial proventriculitis in the hens (Gallus gallusvar. domesticus) were described. Megabacteria isolated from five RossBrown PM-3 hens were Gram and periodic-acid-Schiff positive. B haemolyticrotigh colonies were observed within 48 hours in 5% C02 and 80% humidityat 37 oc on blood agar with added 10% defibrinated sheep blood ...

Chicken (Gallus domesticus) inner ear afferents
Primary Sensory Neuron, 1998Neurons from the vestibular (VG) and the statoacoustic (SAG) ganglion of the chick (Gallus domesticus) were evaluated histologically and morphometrically. Embryos at stages 34 (E8 days), 39 (E13 days) and 44 (E18 days) were sacrificed and temporal bones microdissected.

Haematological parameters dynamics of developing Gallus gallus domesticus
Animal Research International, 2019The blood parameters of 12 broiler chickens (Gallus gallus domesticus) were determined at the ages of 1, 3, 5 and 7 weeks old, for follow-up of the developmental dynamics in their haematological profile. Blood samples were collected from chickens at 7, 21, 35 and 49 days intervals.

Ontogeny of brain temperature regulation in chicks (Gallus gallus domesticus)
British Poultry Science, 19911. Development of brain temperature regulation was studied in the domestic fowl (Gallus gallus domesticus) from hatching to 21 d of age. 2. Body and brain temperature at hatching were relatively low compared with adult levels. However, both were effectively regulated at ambient temperatures of 30 and 35 degrees C, with only a minor difference between ...

Leap orders in male chickens (Gallus gallus domesticus): Longitudinal evidence.
Journal of Comparative Psychology, 1991Leap orders in pairs of male chickens were traced in a longitudinal study from near hatching to about 11 weeks of age. Birds were given a series of 39 day-long social separations, each followed by a day-long reunion. Tests for aggression occurred during the first 5 min of reunion. Pecks were frequent early in the test series, but soon diminished; leaps
