“…differences in migration direction or predefined goal areas; Thorup and Rabøl , Fransson et al , Thorup et al , Liechti et al , Willemoes et al ) they might be more vulnerable to changes and local habitat loss (Taylor and Norris ) than when wintering distributions have the potential to shift (Cresswell ). Population differences in migration directions and wintering locations in pied flycatchers (Chernetsov et al , this study) tend to suggest that wintering site selection is non‐random. A complex pattern of migratory connectivity as observed in this study might be explained by juveniles having predefined goal areas embedded in their genes (Thorup and Rabøl , Fransson et al , Thorup et al , Willemoes et al , contra Cresswell ).…”

“…Despite being one of the ten most abundant passerines in the Afro‐Palearctic flyway (Hahn et al ), our knowledge on their ecology and distribution outside the breeding season is very limited. It is known that pied flycatchers migrate in autumn primarily through the Iberian Peninsula, regardless of their breeding origin, before flying into west‐Africa (Lundberg and Alatalo , Chernetsov et al ). Yet we do not know how pied flycatchers from various breeding areas – with different time schedules – distribute once at their west‐African non‐breeding grounds, and how these migratory connections affect the rest of their annual cycle or their capacity to respond to environmental changes.…”

Understanding what drives or prevents long-distance migrants to respond to environmental change requires basic knowledge about the wintering and breeding grounds, and the timing of movements between them. Both strong and weak migratory connectivity have been reported for Palearctic passerines wintering in Africa, but this remains unknown for most species. We investigated whether pied flycatchers Ficedula hypoleuca from different breeding populations also differ in wintering locations in west-Africa. Light-level geolocator data revealed that flycatchers from different breeding populations travelled to different wintering sites, despite similarity in routes during most of the autumn migration. We found support for strong migratory connectivity showing an unexpected pattern: individuals breeding in Fennoscandia (S-Finland and S-Norway) wintered further west compared to individuals breeding at more southern latitudes in the Netherlands and SW-United Kingdom. The same pattern was found in ring recovery data from sub-Saharan Africa of individuals with confirmed breeding origin. Furthermore, population-specific migratory connectivity was associated with geographical variation in breeding and migration phenology: birds from populations which breed and migrate earlier wintered further east than birds from 'late' populations. There was no indication that wintering locations were affected by geolocation deployment, as we found high repeatability and consistency in d 13 C and d 15 N stable isotope ratios of winter grown feathers of individuals with and without a geolocator. We discuss the potential ecological factors causing such an unexpected pattern of migratory connectivity. We hypothesise that population differences in wintering longitudes of pied flycatchers result from geographical variation in breeding phenology and the timing of fuelling for spring migration at the wintering grounds. Future research should aim at describing how temporal dynamics in food availability across the wintering range affects migration, wintering distribution and populations' capacity to respond to environmental changes.

“…It must have been a map effect, and in first year birds this map must have been inher ited. Our study of West Siberian pied flycatchers also suggested that that these birds may well use innate signposts, maybe based on magnetic parameters (Chernetsov et al, 2008b).…”

At least two independent systems of magnetoreception are currently believed to exist in birds, based on different biophysical principles, located in different parts of their bodies, and with different neu roanatomical mechanisms. One magnetoreceptory system is located in the retina, and may be based on pho tochemical reactions on the basis of cryptochrome. Information from these receptors is processed in a spe cialized part of visual Wulst, the so called Cluster N. There are good reasons to believe that this visual mag netoreceptor processes compass magnetic information necessary for migratory orientation. The second magnetoreceptory system is probably iron based (biogenic magnetite), located somewhere in the upper beak (its exact location and ultrastructure of receptors remain unknown) and innervated by the ophthalmic branch of trigeminal nerve. It cannot be ruled out that this system participates in spatial representation and helps forming either a kind of map or more primitive signpost sense (identification of specific geographic regions), based on regular spatial variation of the geomagnetic field. The magnetic map probably enables navigation of migrating birds across hundreds and thousands of kilometres. Apart from these two systems, whose existence has been convincingly shown (even if some details are not fully clear yet), there is evidence for the existence of magnetoreceptors based on the vestibular system. It cannot be ruled out that iron based magnetoreception takes place in lagena (a part of inner ear in fishes, amphibians, reptiles and birds), and the information per ceived is processes in vestibular nuclei. The very existence of this magnetoreception system needs verification, and its function remains completely open.

“…Both the time (distance) and direction of flight are innate (Gwinner and Wiltschko , Berthold , Helbig , Mouritsen , Mouritsen and Mouritsen ). However, the actual path followed by juvenile birds can be influenced by landscape features and other geophysical factors (Beck and Wiltschko , Thorup and Rabøl , Chernetsov et al ). Juvenile birds on their first autumn migration begin to acquire position‐specific information about their migratory route for future trips.…”

“…Experiments designed to determine the sensory cues used by passerines for positioning show that adult birds can respond to slight variation in some component of the Earth's magnetic field (e.g., inclination and intensity; Fischer et al , Henshaw et al ), and that variation affects something other than the bird's compass sense (Deutschlander et al ). Moreover, some species respond to specific values of the geomagnetic intensity or inclination to indicate locations where they should shift compass directions (Beck and Wiltschko , Chernetsov et al ) or extend stopover duration to refuel and fatten (Fransson et al , Kullberg et al , Henshaw et al ). Thus, passerines are apparently able to determine their location based on characteristics of the geomagnetic field along their migratory route.…”

Site fidelity to breeding and wintering grounds, and even stopover sites, suggests that passerines are capable of accurate navigation during their annual migrations. Geolocator‐based studies are beginning to demonstrate precise population‐specific migratory routes and even some interannual consistency in individual routes. Displacement studies of birds have shown that at least adult birds are capable of goal‐oriented movements, likely involving some type of map or geographic position system. In contrast, juveniles on their first migration use a clock‐and‐compass orientation strategy, with limited knowledge about locations along their migratory routes. Positioning information could come from a variety of cues including visual, olfactory, acoustic, and geomagnetic sources. How information from these systems is integrated and used for avian navigation has yet to be fully articulated. In this review, we (1) define geographic positioning and distinguish the types of navigational strategies that birds could use for orientation, (2) describe sensory cues available to birds for geographic positioning, (3) review the evidence for geographic positioning in birds and methods used to collect that evidence, and (4) discuss ways ornithologists, particularly field ornithologists, can contribute to and advance our knowledge of the navigational abilities of birds. Few studies of avian orientation and navigation mechanisms have been conducted in the Western Hemisphere. To fully understand migratory systems in the Western Hemisphere and develop better conservation policies, information about the orientation and navigation mechanisms used by specific species needs to be integrated with other aspects of their migration ecology and biology.
