Published: 15 June 2013
...Richard Holland; Caterina Filannino; Anna Gagliardo SUMMARY The cues by which homing pigeons are able to return to a home loft after displacement to unfamiliar release sites remain debated. A number of experiments in which migratory birds have been treated with a magnetic pulse have produced...

... cohesion can lead to more accurate outcomes than solitary decisions. In homing pigeons, a classic model in avian orientation studies, individuals learn habitual routes home, but whether and how co-navigating birds acquire and share route-based information is unknown. Using miniature GPS loggers, we...

... upstroke a forward-directed force (thrust) is produced at 36% of body weight. Our propeller measurements for downstroke were consistent with previously published values for a pigeon wing in downstroke posture. Usherwood reports a maximum C L : C D of 5.4 for a pigeon wing spun on a propeller...

... required for level flight and the power necessary for potential energy change. Pigeons ( Columba livia ) were trained to fly at varying angles of ascent and descent (60°, 30°,0°, –30°, –60°), and were recorded using high-speed video. Detailed three-dimensional kinematics were obtained from the recordings...

Pigeon heart mitochondria were isolated with minimal damage to the outer mitochondrial membrane and were incubated at low oxygen pressures...

...Anna Gagliardo; Paolo Ioalè; Maria Savini; Hans-Peter Lipp; Giacomo Dell'Omo Experiments have shown that homing pigeons are able to develop navigational abilities even if reared and kept confined in an aviary, provided that they are exposed to natural winds. These and other experiments performed...

...Monique Maurice; Henri Gioanni; Anick Abourachid SUMMARY We investigated the effects of several behavioural conditions on the properties of the horizontal optocollic reflex (OCR) in pigeons. The head reflex was triggered by rotating the visual surroundings at different velocities (stimuli steps...

We used it to measure the influence of T ASK , T AIR and U WIN on plumage and skin temperatures in pigeons having to dissipate a thermal load while constrained at rest in a flight posture. Our...

...E. Ophir; Y. Arieli; J. Marder; M. Horowitz SUMMARY The heat-acclimated rock pigeon is thought to use cutaneous water evaporation (CWE) as the `preferred' route for heat dissipation, and this mechanism is controlled by adrenergic signaling. In the present study, we tested the hypothesis...

...Helmut Prior; Frank Lingenauber; Jörg Nitschke; Onur Güntürkün SUMMARY The pigeon's use of different visuo-spatial cues was studied under controlled laboratory conditions that simulated analogous aspects of a homing situation. The birds first learned the route to a goal that was not visible...

...Gilead Michaeli; Berry Pinshow SUMMARY We assessed respiratory and cutaneous water loss in trained tippler pigeons ( Columba livia ) both at rest and in free flight. In resting pigeons, exhaled air temperature T ex increased with ambient air temperature T a ( T ex =16.3+0.705 T a ) between 15°C...

Compass senses orient avian flight, but how birds determine their location in order to select the correct homeward bearing...

To learn whether birds are able to take the different rates of sun azimuth change into account, we subjected homing pigeons to a 4 h fast clock-shift. The experiments were performed near Auckland, New Zealand...
