Migratory birds are hardy and versatile animals, throughout their lives, run an equivalent distance between the earth and the moon. Every year between their shifts now toward the Arctic tundra to start the reproductive period, now heading for the Neotropical region for wintering sites with abundant food, they need to access various environments that do not respect geopolitical boundaries. Over the years, it has been noticed a reduction of many of these birds populations worldwide. Climate change and anthropogenic factors, especially in the vicinity of coastal areas may be the motivators of this scenario. The conservation of species and habitats used by them requires an international effort to plan global policies and actions, but acting regionally in strategic locations for these species. Thus, this thesis was to analyze the possible pressures on populations of Nearctic migratory birds of Charadriidae and Scolopacidae families who frequent the island airplane Crown, in the municipality of Igarassu, Pernambuco, and its respective population behavior. To this were accessed as a research tool local knowledge 240 traditional fishermen in the municipalities of Igarassu, Itapissuma and Itamaracá that were linked to a local colony. It was also performed a collection of ornithological data from conducting a census in place with duration of 29 months and will perform a geoprocessing work of the surrounding area of ​​the island. Similarly, if confronted with the current data surveys conducted by other researchers in previous periods. The results found that the knowledge and the wealth of information that fishermen have on migratory birds and migration periods. The analysis of the actual census indicated that some species possibly less sensitive to changes in the environment are increasing their abundance in preference to the current outras.Quando compared with previous census, it was found that some of the waders species that attend the place delayed in at least one month his arrival at the wintering site, which may be related to changes in the global environment. Finally, we recorded the occurrence of resident species breeding in Airplane Crown Island.
