Birds in their first nuptial plumagemay now be distinguished from fully mature birds by their browner wings andtail and, often, less intensely black body feathers. At the postnuptial or fall molt, which, as usual, is complete, the birdassumes a costume somewhat like that of the first winter; but the tail and wing-quills are now fully black and there is more black on the WOOD PEWEEPhotographed by Guy A. Bailey, Geneseo, N. Y. A Cooperative Study of Bird Migration ^LTHOUGH we received seventy-one reports on the migration of the/\ first group of birds—Robin, Red-winged Blackbird and Phoebe—(including five that were held and sent with the second group), onlyforty-four reports on the Chimney Swift, House Wren and Baltimore Oriolehave come in. Therefore we cannot make such comparisons nor come to suchconclusions as might have been possible from a larger number of returns. Itwould have been interesting, for instance, to see whether the Swifts reachedNova Scotia from the mainland, as the Robins apparently did, or enteredthe south end directly, from over the water. The migration of the present three species called forth few comments asto its being unusual in any way. Pittsburgh reported all three as being uncom-monly early, Milwaukee that the Oriole was four days ahead of its record,and New Haven that the Swift and Wren were late. For all th
