Singing behavior on the ground and in trees is discussed. Swainson?s Warblers sing vigorously from the time they arrive on the breeding ground until the latter part of June, when the singing of most birds becomes more sporadic. At Macon, Georgia, in mid-April, morning song of one bird began about 20 minutes before sunrise; and evening song of the same bird ceased about 15 minutes after sunset. Songs were delivered at the rate of about 8-9 per minute for the first few minutes of morning song, decreasing to 5-6 per minute for most of the morning. Songs are given in courses or series. The rate of singing is usually faster at the beginning of a course. The number of songs sung by a territorial male in 1 day in the Dismal Swamp, Virginia, 2 June, was 1168. It produced 280 songs the first hour, and sang at a fairly constant rate from 5:00 to 8:00 AM, 192, 194, 198 songs per hour.

Included in the study were Cnephia dacotensis (Dyar & Shannon), C. mutata (Malloch), Prosimulium fuscum Syme & Davies, Simulium aureum Fries, S. decorum (Walker), S. venustum Say, S. verecundum Stone & Jamnback, and S. vittattum Zetterstedt. Simuliid eggs collected from a variety of habitats, packed with wet materials in plastic bags and held at 4°C, have remained viable, thus far, up to 424 days. Eggs held at 0° to −70°C failed to hatch when placed in rearing aquariums. Air-dried eggs held at 4°C for 339–535 days failed to hatch after being held in aquariums for 166 days. Immature stages of black flies were successfully reared in 1¼-gallon Pyrex jars and 15-gallon plexiglas aquariums in which the water was agitated by compressed air and aquarium pumps. Water velocities of 0.250–0.542 feet per second were obtained in streams of air bubbles created by use of air stones. Of 21 larval diets used, one consisting of Purina Dog Chow (60-mesh or finer), brain-heart infusion broth, and brewer's yeast powder, and a second consisting of Wayne's dog chow (60-mesh or finer) and brain-heart infusion broth without brewer's yeast powder, were most satisfactory. Larvae were fed 1 gram of diet per 1¼- gallon aquarium and 2 grams per 15-gallon aquarium biweekly. In most of the 225 cultures of S. aureum, S. decorum, S. verecundum, S. venustum, and S. Vittatum it took from 1 to 5 days for the development of eggs to larvae (165 cultures, 73%) and the same number of days for the development of pupae to adults (172 cultures, 76%). Development time for larvae to pupae was fairly closely divided between 11–15 days (63 cultures, 28%) and 16–20 days (53 cultures, 23.6%). The entire period for development from egg to adult after placement of eggs in rearing aquariums was from 21 to 25 days for 26.7% of the cultures.

Buttonbush was the primary choice; it was used to support 50 of the 177 nests. Silverling and willow were the next most often used plants. Nests also were found in other shrubs and trees, in assorted herbs and grasses, and in fields of sweet corn and sugarcane. The great degree of nesting adaptability of the Red-winged Blackbird is attested by the diversity of nesting site selections in several habitats.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wilson Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Stowers, J., Harke, D., and Stickley, A., 1968, Vegetation used for nesting by the red-winged blackbird in Florida: The Wilson Bulletin, v. 80, no. 3, p. 320-324.","productDescription":"320-324","startPage":"320","endPage":"324","numberOfPages":"5","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":193474,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":15857,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://elibrary.unm.edu/sora/Wilson/v080n03/p0320-p0324.pdf","linkFileType":{"id":1,"text":"pdf"}}],"volume":"80","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a14e4b07f02db60254f","contributors":{"authors":[{"text":"Stowers, J.F.","contributorId":47473,"corporation":false,"usgs":true,"family":"Stowers","given":"J.F.","email":"","affiliations":[],"preferred":false,"id":331305,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Harke, D.T.","contributorId":78422,"corporation":false,"usgs":true,"family":"Harke","given":"D.T.","email":"","affiliations":[],"preferred":false,"id":331306,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stickley, A.R.","contributorId":16519,"corporation":false,"usgs":true,"family":"Stickley","given":"A.R.","affiliations":[],"preferred":false,"id":331304,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":5220204,"text":"5220204 -
