There are many theories about how migrating birds navigate as Wehner explains in his Perspective. He discusses new findings obtained with radar on a Canadian coast guard icebreaker vessel, which show that Arctic seabirds are able to faithfully follow the great-circle (orthodrome) routes of far northern latitudes most probably by steering with their sun compass while keeping their internal clock out of phase with local time ( Alerstam et al .). 
Can vector summation describe the orientation system of juvenile ospreys and honey buzzards? - An analysis of ring recoveries and satellite tracking
Juvenile bird migrants are generally believed to use a clock-and-compass migratory orientation strategy. According to such a strategy migrants accomplish their migration by flying a number of

Predicted flight trajectories differ depending on which orientation cues are used by migrating birds. Results from radar and satellite tracking of migrating birds can be used to test which of the
Understanding the migratory orientation program of birds: extending laboratory studies to study free-flying migrants in a natural setting.
TLDR
Progress in understanding certain components of the migration-orientation system is focused on, which provides fundamental insights into the nature of the migratory orientation system that enables experienced birds to navigate and guide inexperienced, young birds to their species-specific winter grounds.
Compensatory behaviour after displacement in migratory birds
TLDR
Using a meta-analysis approach, orientation cage experiments with displaced migrants found in the literature were re-analysed, showing a role for the stars to be involved in detection of the changes in position.

Hypoxia upregulates VEGF expression in alveolar epithelial cells in vitro and in vivo.
TLDR
Findings suggest that release of VEGF synthesized by AEC may target not only endothelial cells but also other alveolar cells, including macrophages and epithelial cells, as well as bronchoalveolar lavage fluid.

Migration along orthodromic sun compass routes by arctic birds.
TLDR
Flight directions of birds migrating at high geographic and magnetic latitudes can be used to test bird orientation by celestial or geomagnetic compass systems under polar conditions, showing changing geographic courses as the birds traverse longitudes and their internal clock gets out of phase with local time.
Magnetic Orientation in Animals
This text details animal orientation with the help of information from the geomagnetic field. It reviews the magnetic effects on spatial behaviour in the various groups of the animal kingdom from
Magnetic information affects the stellar orientation of young bird migrants
WHEN young birds leave on their first migration, they are guided by innate information about their direction of migration. It is generally assumed that this direction is represented twice, namely

TLDR
The orientation system of the Savannah sparrow is typical of nocturnal migrant passerine birds, based on a system of interacting compass senses: magnetic, star, polarized light and, perhaps, sun compasses.
Modelling migration: the clock-and-compass model can explain the distribution of ringing recoveries
TLDR
It is suggested that at least young pied flycatchers, and perhaps night-migrating passerines in general, use a simple clock-and-compass strategy to reach their wintering area, and all the prerequisites (a compass and an internal clock) that they need to orient during migration seem to be known at present.

TLDR
The genetic basis, mode of inheritance and recent evolutionary changes of migratory directions in birds are discussed on the basis of published and new experimental evidence and new data on the orientation of an F2 generation suggest that the directional information is encoded by only a few major genes.
