VIctor, I can help concerning marine turtles. Yo can visit Marine Turtles Newlwter (see link) and seaturtles.org. Here, under "ressources" there are information on tagging, migration, etc., but on marine turtles
"Animal Migration" is a new journal exclusively focused on this general topic:

"Movement Ecology" is another open-access option:
http://www.movementecologyjournal.com/
Otherwise, "Ecology" and "Journal of Animal Ecology" have published a lot of work on wildlife migration, ranging from movement studies to physiology to disease modeling.
Another journal, not entirely devoted to bird migration, but very good, is JOURNAL OF AVIAN BIOLOGY. There are some papers about bird migration in it...
