Climate change is increasingly disrupting global migratory bird patterns by creating mismatches between migration timing and food availability. In Mexico, species such as Mississippi kites and various aquatic birds utilize coastal corridors in Veracruz to travel from North America toward Central and South ~~America. However, scientists warn that rising temperatures may cause birds to arrive at destinations after the peak abundance of essential food sources like insects and caterpillars has passed.~~ America, often synchronizing their movement with migratory dragonflies. In Europe, research indicates that long-distance migratory species are facing population declines due to a lack of suitable resting habitats. Specific environmental shifts, such as the drying of shallow lakes and earlier ripening of berries, are altering migratory behavior. In Hungary, insectivorous birds risk missing peak food abundance, while storks are showing altered patterns, including congregating at landfills rather than traditional wetlands and exhibiting more abrupt departures from villages. In Northern Greece, studies of wetland, forest, and agricultural ecosystems show that weather conditions significantly impact species distribution. For instance, waterfowl may initially increase in Northern Greek wetlands during cold spells as they seek milder climates, but may continue to more southern regions if extreme weather persists and food becomes scarce. Additionally, woodcocks in forest ecosystems have been observed abandoning mountainous areas for lower altitudes during intense cold periods to find more favorable conditions.
