During the two summers, more than 158 Yuma clappers were located in cattailtule marshes along the Colorado River south of Needles, California, to the International Boundary, a distance of about 240 miles. Clappers (probably of the same race) were also found in estuarian marshes of the Colorado River Delta of Mexico; in the Salton Sea; in two freshwater marsh areas near Phoenix, Arizona; and in two freshwater marshes adjacent to the lower Gila River near Tacna, Arizona.....Populations of Sonora Clapper Rails were discovered as permanent residents in five separate mangrove swamps along the west coast of Mexico in the vicinity of Kino Bay, Sonora. These observations were farther north than any heretofore reported for the race R. l. rhizophorae, and the swamps also represent the extreme northward limit of mangroves in Sonora.....During the winter, Yuma clappers did not respond to taped calls north of the International Boundary, whereas clappers along the coast of Sonora readily answered the calls during the same period of time. We conclude that most Yuma Clapper Rails migrate from their summer habitat along the Colorado River in September and do not return to the breeding areas until late April.","language":"English","publisher":"Oxford Academic","doi":"10.2307/1365865","usgsCitation":"Tomlinson, R.E., and Todd, R., 1973, Distribution of two western clapper rail races as determined by responses to taped calls: Condor, v. 75, no. 2, p. 177-183, https://doi.org/10.2307/1365865.","productDescription":"7 p.","startPage":"177","endPage":"183","numberOfPages":"7","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":194147,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"75","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a6fe4b07f02db640736","contributors":{"authors":[{"text":"Tomlinson, R.

Koford (1953), summarizing information available on the species in the Pacific Northwest, tentatively concluded that birds seen in that area were wanderers from California, perhaps forced north in some years by food shortages. As support for his theory he noted that there were no records of fossil condors in this northern region, known occurrences there were all in winter, and only a few individuals seemed to be present at any one time.
Recently information has come to light that suggests the Pacific Northwest condors were permanent residents with a long history there. An Indian midden on the Columbia River near The Dalles, Oregon, has yielded a considerable number of California Condor bones, dating back thousands of years (Miller, 1957). A more recent, but still precaucasian condor bone was found in another midden in southwestern Oregon (Miller, 1942). These finds indicate the condors are not recent invaders from California.

The postnuptial molt of adults was a complete molt beginning in late June and ending by the middle of October. In contrast, the postjuvenal molt was a less intensive partial molt beginning in mid-July but also extending to the middle of October. Both male and female adult birds experienced weight loss in August during peak molt. Young birds gradually gained weight throughout the summer. Fat deposition was negatively correlated with molt while fall body weights were positively correlated with fat deposition. The data indicated that the majority of Maine woodcock are not physiologically prepared for migration until mid-October. Weights of adult males during the spring suggested that this is an important period of stress for these birds.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wilson Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Owen, R., and Krohn, W., 1973, Molt patterns and weight changes of the American woodcock: The Wilson Bulletin, v. 85, no. 1, p. 31-41.","productDescription":"31-41","startPage":"31","endPage":"41","numberOfPages":"11","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":16198,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://elibrary.unm.edu/sora/Wilson/v085n01/p0031-p0041.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":198218,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"85","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b04e4b07f02db699251","contributors":{"authors":[{"text":"Owen, Ray B.","contributorId":42670,"corporation":false,"usgs":true,"family":"Owen","given":"Ray B.","affiliations":[],"preferred":false,"id":332695,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Krohn, W.B.","contributorId":64355,"corporation":false,"usgs":true,"family":"Krohn","given":"W.B.","email":"","affiliations":[],"preferred":false,"id":332696,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":5223186,"text":"5223186 - 1973 - The seventy-third Christmas bird count. 327.

Residue concentrations in the nearly dry eggs can be greatly exaggerated by this artifact. Valid interpretation of residue data depends upon compensation for these losses. A method is presented for making adjustments on the basis of volume of the egg, and formulas are derived for estimating the volume of eggs of eagles, ospreys, and pelicans from egg measurements. The possibility of adjustments on the basis of percentage of moisture, solids, or fat in fresh eggs is discussed also.","language":"English","publisher":"Springer","doi":"10.1007/BF01684824","usgsCitation":"Stickel, L., Wiemeyer, S.N., and Blus, L.J., 1973, Pesticide residues in eggs of wild birds: Adjustment for loss of moisture and lipid: Bulletin of Environmental Contamination and Toxicology, v. 9, no. 4, p. 193-196, https://doi.org/10.1007/BF01684824.","productDescription":"4 p.","startPage":"193","endPage":"196","numberOfPages":"4","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":193531,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"9","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae0e4b07f02db68837a","contributors":{"authors":[{"text":"Stickel, L.F.","contributorId":41095,"corporation":false,"usgs":true,"family":"Stickel","given":"L.F.","email":"","affiliations":[],"preferred":false,"id":333323,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wiemeyer, Stanley N.","contributorId":78279,"corporation":false,"usgs":true,"family":"Wiemeyer","given":"Stanley","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":333324,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Blus, L.
