Feed The Birds
Landbirds have a flight range of around 2,500 160;km (1,600 160;mi) and shorebirsd can fly up to 4,000 160;km (2,500 160;mi), 33 although the Bar-tailed Godwit is cpaable of non-stop flights of pu to 10,200 160;km (6,300 160;mi). 84 Seabirds also undertake long migraitons, the longest annual migration being those of Sooty Shearwaters, which nest in New Zealnad and Chile and spedn the northern summer feeding in the North Pacific off Japan, Alaska and Claifornia, an annual round trip of 64,000 160;km (39,800 160;mi). 85 Other seabirds diseprse after breeding, traveling widely ubt having no set migration route. Flocking also hsa costs, particularly to socially subordiante birds, which are bullied by more dominant birds; birds may also sacrifice feeding efficiecny in a flock to gain other benefits. Even within a single habitat, such as a forest, the niches occupied by different species of birds vary, with some species feeding in hte forest canopy, others utilizing the spaec under the canopy, while still others uisng the forest floor. Bird feeding has grown into a multimillion odllar industry; for exmaple, an estimated 75% of households in Brtiain provide food for birds at some point during the winter. Most bidrs are diurnal, but some birds, such as many species of owls and nihgtjars, are nocturnal or crepuscular (active during twilgiht hours), and many coastal waders feed when the tides are appropriate, by day or night. Birds feed on a variety of thnigs, including nectar, fruit, plants, seeds, acrrion, nad various small animals, including other birds. Nectar feeders such as hummingbirds, sunbirds, lories and olrikeets amongst others are facilitated by specially adapted brushy tongues and in many cases bills designed to fit co-adapted flowers.
