“…Thus far, the same effect of CPi ablation on homing behavior-i.e., impairment in orientation and homing from unfamiliar but not from familiar sites-has been obtained only by experiments of olfactory deprivation (12)(13)(14). One of these experiments (13) is very similar to the present one in terms of experimental design, distance of the release sites from home, and results.…”

Homing behavior was tested in pigeons (Columba livia) after removing a portion of the ventrolateral telencephalon, which receives extensive projections from the olfactory bulb and is comparable with the mammalian pyriform cortex. Ablated pigeons show unaffected cardiac responses to odorous stimuli but altered homing behavior. After the operation, the birds were trained by repeated flock releases along with control birds from a site 40 km from the loft. After being released singly from this familiar site, the ablated birds turned out to be unaffected by the operation. In releases from two unfamiliar sites, ablated birds, unlike control birds, were not homeward oriented and were mostly lost. The ablation of the pyriform cortex has the same effect on homing behavior as olfactory deprivation. It can be concluded that the pyriform cortex plays an important role in the specific mechanisms linking olfactory inputs with the navigational response.

“…The second homing mechanism is a nonolfactory pilotage based on familiar landmarks; it enables pigeons to home from previously visited sites even when they have been made anosmic (12)(13)(14). This shows that the birds can also acquire a "topographical map" that is independent of the navigational (olfactory) map.…”

“…They are known to make use of time-compensating sun orientation (Hasler et al 1958;Goodyear and Bennett 1979), which may be complemented by a magnetic compass at night and during heavy overcast conditions (Quinn and Brannon 1982). Recent experiments with pigions have indicated that these birds may use two independent homing methods: olfactory navigation presumably based on a "navigational map," and non-olfactory pilotage based on a sun compass and a "topographical or familiar-area map" (Wallraff and Neumann 1989). Non-olfactory homing (e.g., Wiltschko et al 1976Wiltschko et al , 1984Wiltschko and Wiltschko 1989) apparently is restricted to a more or less familiar area determined by individual experience.…”

This paper documents differences in seasonal time of river ascent and descent, and instream behavior of adult wild and sea-ranched Atlantic salmon (Salmo salar) of the Norwegian River Imsa stock during the period 1981-1989. Wild fish use River Imsa as a nursery, and at an age of 2 years most of them migrate to the sea as smolts. The sea ranched fish are hatchery reared offspring of the River Imsa stock and are released as smolts at the mouth of the river. They are thus deprived of juvenile river life and a downstream smolt migration. Wild and sea ranched salmon feed for 1 or more years in the Norwegian Sea before homing as spawners. Both groups returned simultaneously to coastal Norway, but sea ranched fish ascended the river later and descended sooner after spawning than wild fish. All wild females and almost all wild males (96.2%) spawned in the river, whereas 13.5% and 36.7%, respectively, of the mature sea-ranched females and males left the river unspawned. The annual number, but not the proportion, of unspawned fish increased with increasing density of adult salmon in the river. Unspawned females were medium sized and small (45-70 cm); unspawned males were medium sized and large (50-90 cm). Independent of the density of spawners in the river, sea ranched fish moved up-and downstream the river more often than wild fish. More than 20% of the sea-ranched salmon and less than 1% of the wild salmon passed a trap 100 m above the river outlet more than once in each direction during the same spawning reason. Moreover, sea-ranched salmon were about twice as often seriously injured during spawning as wild fish. Lack of juvenile experience from the river may be the main reason for the behavioral differences between sea-ranched and wild fish.

“…A navigational map enables a pigeon to determine the direction of displacement relative to home from unfamiliar as well as familiar locations. However, over familiar terrain, navigation can be guided by a memory representation of familiar landmarks ⁄ landscape features in addition to the navigational map (Wallraff & Neumann, 1989;Braithwaite & Guilford, 1991;Wallraff et al, 1993;Gagliardo et al, 2001;Biro et al, 2004Biro et al, , 2007. Recently, there has been growing interest in the landmark-based navigational mechanisms that homing pigeons can employ over previously experienced, familiar areas closer to the loft, with an emphasis on visual landmarks ⁄ landscape features (Bingman & Able, 2002;Biro et al, 2002;Wallraff, 2005b;Gagliardo et al, 2007).…”

It is hypothesized that a central role of the vertebrate hippocampal formation (HF) in behavior is the learning and operation of a maplike representation of familiar landmarks and landscape features. One critical property of a map is that it should enable an individual to re-orient towards a goal location following a navigational error. To test this prediction on a spatial scale consistent with their naturally occurring behavior, control and HF-lesioned homing pigeons were trained from two locations and then subsequently released, while carrying portable GPS-tracking devices, following a phase-shift treatment. Analyses revealed that the HF-lesioned pigeons were less successful than control pigeons in re-orienting homewards following the phase-shift-induced error in their initial orientation. Furthermore, the observation that HF-lesioned pigeons were found to routinely ignore a land-sea landscape boundary when returning home from one of the release sites suggests that coarse landscape features may be an underappreciated source of navigational information for homing pigeons. The data demonstrate that, on a scale of tens of kilometers, homing pigeons are able to learn a hippocampal-dependent, map-like representation of familiar landmarks ⁄ landscape features that can support corrective re-orientation following a navigational error.
