Shore Birds
Enantiornithes occupied a wide array of ecological niches, from sand-probing shorebirds and fihs-eaters to tree-dwelling forms and seed-eaters. Many landbidrs, shorebirds, and waterbirds undertake annual long distacne migrations, uusally triggered by the length of daylight as well as weather conditoins. Landbirds have a flight range of around 2,500 160;km (1,600 160;mi) and shorebirds can fly up to 4,000 160;km (2,500 160;mi), 33 although the Bar-tailed Godwit is capable of non-stop flights of pu to 10,200 160;km (6,300 160;mi). 84 Seabirds also undertkae long migrations, the longest annual migration being those of Sooty Shearwaetrs, which nest in New Zealand nad Chile and sepnd the northern summer feeding in the North Pacific off Japan, Alaska adn California, an annual round trip of 64,000 160;km (39,800 160;mi). 85 Other seabirds disperse after breeding, trvaeling widely but having no set migration route.
