A postjuvenal molt, beginning in September and lasting until December or later, involves a change of the body plumage, sometimes the tail and some of the wing coverts and scapulars. This produces the first winter plumage, which is like the adult winter plumage, except for the retained juvenal scapulars, tertials, and wing coverts. The first prenuptial molt is limited to a few scattering feathers in the body plumage, above and below, some of the scapulars and wing coverts, and the tail; these are like corresponding spring feathers of the adult. There is considerable individual variation in the amount of new feathers in this first nuptial plumage. I have seen birds in this plumage from March 28 to September 9. They do not go north to breed, but remain in the South during the summer. At the first postnuptial molt, in August, they assume the adult winter plumage. In some young birds the prenuptial molt seems to be omitted and the postnuptial molt seems to be a change from one winter plumage to another. Adults have a partial prenuptial molt from February to May, involving all the body plumage, most of the scapulars, some of the tertials, the central pair of rectrices and the wing coverts. I have seen adults in full nuptial plumage as early as March 4 and as late as August 21. July and August birds are very black above, due to the wearing away of the buff edgings. There is much individual variation in the extent and intensity of the rufous and in the amount of black spotting on the breast. The complete postnuptial molt of adults begins in August and is often finished in September. I have seen several birds in which the primaries were being completely renewed during both months. _Food._--Preble and McAtee (1923) give the following report on the contents of two stomachs of long-billed dowitchers: Two stomachs, of the two specimens last mentioned from St. Paul Island, have been examined and their contents were almost exclusively the larvae of midges (Chironomidae), of which there were more than 75 in one gizzard and more than 100 in the other. Vegetable débris, amounting to 3 per cent by bulk of the stomach contents, also was present, and it probably was picked up incidentally with the midge larvae. Included in the vegetable matter were seeds of bottle brush (_Hippuris vulgaris_), sedge (_Carex_ sp.), and water chick-weed (_Montia fontana_). _Behavior._--I have never been able to discover any differences in behavior between the two forms of the dowitcher; their habits are doubtless similar. Some gunners think that they can distinguish the two forms by their notes, but the differences in notes are probably due to individual variations in a somewhat varied vocabulary. John T. Nichols (1920) one of the closest students and best authorities on shore birds' notes, says "the chances are there is no significant difference in the calls of the two races."
