Migratory animals capable of navigating to a specific destination, and of compensating for an artificial displacement into unfamiliar territory, are thought to have a compass for maintaining their direction of travel and a map sense that enables them to know their location relative to their destination. Compasses are based on environmental cues such as the stars, the Sun, skylight polarization and magnetism, but little is known about the sensory mechanism responsible for the map sense. Here we… 
Progress in Studies of Geomagnetic Navigation of Animals
The geomagnetic field may play a key role in orientation and navigation of many long-distance migratory animals. Taking homing and migrating birds as examples, this paper reviews recent progress in
Sea turtles, lobsters, and oceanic magnetic maps
TLDR
Unraveling the nature of magnetic maps and exploring how they are used represents one of the most exciting frontiers of behavioral and sensory biology.

Geomagnetic Navigation and Magnetic Maps in Sea Turtles
: Sea turtles can extract two types of navigational information from Earth's magnetic field: (1) directional or compass information; and, (2) positional or map information useful in assessing
Magnetic Orientation and Navigation in Marine Turtles, Lobsters, and Molluscs: Concepts and Conundrums1
TLDR
Findings in the brain of T. diomedea represent an encouraging step toward a holistic understanding of the cells and circuitry that underlie magnetic orientation behavior in one model organism.
Sea Turtles: Navigation and Orientation
Magnetic maps in animal navigation
TLDR
Recent findings indicate that sea turtles, salmon, and at least some birds imprint on the magnetic field of their natal area when young and use this information to facilitate return as adults, a process that may underlie long-distance natal homing (a.k.a. natal philopatry) in many species.

Long-distance navigation in sea turtles
Adult sea turtles of several species migrate across vast expanses of ocean to arrive at specific nesting areas and feeding sites. Two hypotheses have been proposed to account for this remarkable

TLDR
It is demonstrated that sea turtles can distinguish between different magnetic inclination angles and perhaps derive from them an approximation of latitude.
Avian navigation: from historical to modern concepts
Studies on avian navigation began at the end of the 19th century with testing various hypotheses, followed by large-scale displacement experiments to assess the capacity of the birds' navigational
The map sense of pigeons
TLDR
Homing pigeons are able to return to their lofts after displacement to unfamiliar sites hundreds of kilometres away, and recent experiments implicate magnetic and olfactory cues as the basis of the mysterious map sense.
Loggerhead sea turtles
The stunning photo on the cover of the Loggerhead Sea Turtles book, coupled with its generic title, might lead one to believe that this is a book for popular audiences. But please don't judge this
Migration of green (Chelonia mydas) and loggerhead (Caretta caretta) turtles to and from eastern Australian rookeries
TLDR
Feeding-ground captures of green and loggerhead turtles tagged while nesting at eastern Australian rookeries over a 21-year period are summarised and migratory behaviour, imprinting and navigation are discussed.
Site fidelity and homing behavior in juvenile loggerhead sea turtles (Caretta caretta)
TLDR
The results of this study indicate that juvenile loggerheads exhibit fidelity to specific areas during summer months and possess the navigational abilities to home to these areas following forced displacements and long-distance migrations.
The concepts and terminology of bird navigation
TLDR
A unified set of terminology used to refer to orientation and navigation behaviour have acquired varied and divergent meanings is presented that is hoped will help clarify thinking and communication in the field.
