Abstract
Eight netting stations were set up in Stann Creek Valley, British Honduras, during 6 successive expeditions in March and April 1960-1965. In 1965, from 18 March through 23 March, 2 netting stations were set up in the vicinity of La Lima, Honduras. Returns are summarized for northern migrants to the same winter quarters, and the period from banding to return. Of the 41 spp. of Parulidae in Russell''s monograph, 37 spp. are northern migrants. Of these 37 northern migrants spp. the author banded 27, or 72.9%. Returns were had to winter quarters on 10 spp., or 37% of those banded by the author. Seven recoveries are shown of orchard orioles banded in British Honduras and recovered from latitude 33[degree] and longitude 91[degree], to latitude 41[degree] 40" and longitude 81[degree]. Repeats, returns, and recoveries are listed for birds that were banded at La Lima, Honduras, from the late fall of 1963 through the early spring of 1965. The repeats and returns were captured by the author during his expedition and correlated with the banding data of Hamilton and Wilson. Recoveries were obtained from the Fish and Wildlife Service. Most records of the return of northern migrants to identical tropical winter quarters anywhere in the world have been obtained within recent years since the use of mist nets in banding. Studies of habitats; time of day of best catches; roosting and feeding areas; abundance of both northern migrants and endemics; and undoubted proof of winter residence of northern migrants were obtained. Apparently, recoveries and migrants banded in tropical winter quarters in migration from more southern areas and recaptured during migration or in northern nesting areas are even more uncommon than returns to tropical winter quarters. This, too, appears to be the result of more recent netting operations in tropical areas by a larger number of banders.
