Should we terminate an 'artificial,' tree-nesting raptor population in Arizona?
D. H. Ellis, D.G. Smith, F.B.P. Trahan
1994, Journal of Raptor Research (28) 56 (abs)
The Altar Valley in southcentral Arizona was once a iallgrass prairie. Overgrazing prevented fire and spread mesquite, allowing the area, now a savanna, to be heavily used by tree-nesting raptors in summer and heavily hunted by perch-hunting raptors in winter. The breeding raptor community (over 150 pairs) consists primarily of...
Diurnal raptors in the fragmented rain forest of the Sierra Imataca, Venezuela
E. Alvarez, D. H. Ellis, D.G. Smith, C.T. LaRue
1994, Journal of Raptor Research (28) 45 (abs)
The rain forest of the Sierra Imataca in eastern Venezuela has been subjected to extensive deforestation for pastures and agricultural settlements. In the last decade the opening of access roads combined with intensified logging and mining activities have fragmented a significant portion of the remaining forest. We noted local distribution...

1994, Science (266) 1835-1839
In the course of 71 days in lunar orbit, from 19 February to 3 May 1994, the Clementine spacecraft acquired just under two million digital images of the moon at visible and infrared wavelengths. These data are enabling the global mapping of the rock types of the lunar...
Survival rates of American woodcock wintering along the Atlantic coast
David G. Krementz, John T. Seginak, David R. Smith, Grey W. Pendleton
1994, Journal of Wildlife Management (58) 147-155
Because American woodcock (Scolopax minor) populations have been declining, we attached radio transmitters to woodcock at coastal plain sites to determine if survival during winter was involved in the decline. Sites were in Georgia (1982-84, 1989-92), South Carolina (1988-89), and Virginia (1991-92). Survival rates were not different between age or...
Surface- and ground-water quality data at selected landfill sites in Mecklenburg County, North Carolina, 1979-92
D.G. Smith
1993, Open-File Report 93-437
The U.S. Geological Survey initiated an urban water-quality study in 1979 in cooperation with the City of Charlotte and Mecklenburg County, North Carolina. As part of this study, a water-quality monitoring network was established at selected landfill sites in Mecklenburg County. Water-quality samples were collected at 27 surface-water sites and...
The Hatu gold anomaly, Xinjiang-Uygur Autonomous Region, China - testing the hypothesis of aeolian transport of gold
D.B. Smith, P. K. Theobald, S. Shiquan, R. Tianxiang, H. Zhihui
1993, Journal of Geochemical Exploration (47) 201-216
In 1987, a cooperative project between the U.S. Geological Survey and the Institute of Geophysical and Geochemical Exploration was initiated to evaluate the origin of the Hatu gold anomaly. The anomaly is located in the Hatu mining district in the northwest corner of Xinjiang-Uygur Autonomous Region in northwest China. The...
Determining sex of eastern screech-owls using discriminant function analysis
D.G. Smith, Stanley N. Wiemeyer
1992, Journal of Raptor Research (26) 24-26
Seven morphometric characteristics and weight of males and females of a captive colony of Eastern Screech-Owls (Otus asio) were compared. Females were significantly larger than males in weight, total length, and length of tail, wing and bill. A discriminant function analysis based on weight, wing and tail length...
Techniques for rearing and releasing nonmigratory cranes: Lessons from the Mississippi Sandhill Crane program
D. H. Ellis, Glenn H. Olsen, G.F. Gee, Jane M. Nicolich, K.E. O'Malley, Meenakshi Nagendran, Scott G. Hereford, P. Range, W.T. Harper, R.P. Ingram, D.G. Smith
1992, Book chapter, Proceedings of the Sixth North American Crane Workshop.
Captive-reared Mississippi sandhill cranes (Grus canadensis pulla) reared at the Patuxent Wildlife Research Center (Patuxent) have been released at the Mississippi Sandhill Crane National Wildlife Refuge (MSCNWR) since 1981. Of 131 birds released through December 1990, 103 were reared by foster parents. The remaining 28 were experimentally hand-reared in 1989...
Population recovery of the Whooping Crane with emphasis on reintroduction efforts: Past and future
D. H. Ellis, J. C. Lewis, G.F. Gee, D.G. Smith
1992, Book chapter, Proceedings of the Sixth North American Crane Workshop.
The U.S. Fish and Wildlife Service (USFWS) began building a captive whooping crane (Grus americana) colony at Patuxent Wildlife Research Center (Patuxent), Maryland, in 1966. From 1976 to 1984, 73 eggs from this colony and 216 eggs from Wood Buffalo National Park (Wood Buffalo), Canada, nests were placed in sandhill...
Progress in satellite tracking cranes
D. H. Ellis, D.G. Smith, Glenn H. Olsen, M.R. Fuller, S.E. Landfried, H. Higuchi, C.H. Vermillion
1992, Book chapter, Proceedings of the Sixth North American Crane Workshop
We review the history of tracking cranes with satellite telemetry and identify some of the difficulties in designing satellite transmitters and harnesses for cranes. Miniaturization of these transmitters and a plethora of harnessing experiments since 1989 allow us to recommend limited application of this technology to all species of cranes....
Past and potential contributions of captive breeding to population recovery of the Whooping Crane
D. H. Ellis, G.F. Gee, D.G. Smith
1991, Book chapter, Acta XX Congressus Internationalis Ornithologici, Volume 4
A captive Whooping Crane colony was established at the Patuxent Wildlifa Research Center in Maryland in 1966. This colony first produced eggs in 1975 and has produced 252 eggs through 1990. From 1976 to 1984, 73 eggs were sent Io Grays Lake, Idaho, the site of the first Whooplng Crane...
Images from Galileo of the Venus cloud deck
M. J. S. Belton, P.J. Gierasch, M. D. Smith, P. Helfenstein, P.J. Schinder, James B. Pollack, K.A. Rages, A.P. Ingersoll, K.P. Klaasen, J. Veverka, C.D. Anger, M. H. Carr, C. R. Chapman, M. E. Davies, F. P. Fanale, R. Greeley, R. Greenberg, J. W. Head III, D. Morrison, G. Neukum, C.B. Pilcher
1991, Science (253) 1531-1536
Images of Venus taken at 418 (violet) and 986 [near-infrared (NIR)] nanometers show that the morphology and motions of large-scale features change with depth in the cloud deck. Poleward meridional velocities, seen in both spectral regions, are much reduced in the NIR. In the south polar region the markings in...
Raptor road surveys in South America
D. H. Ellis, R.L. Glinski, D.G. Smith
1990, Journal of Raptor Research (24) 98-106
Twenty-six (23 traveling and three point) raptor roadside surveys were conducted during a 29,000 km expedition through nine nations of South America. During roadside surveys, we tallied 41 of the 87 (47%) diurnal raptor species (including vultures) that occur in South America. The number of species observed per route varied...
[Book review] Return of the Whooping Crane
D. H. Ellis, D.G. Smith
1990, The Auk (107) 812-814
Fewer than 40 years ago, Life magazine ran an article decrying the plight of Whooping Cranes (Grus americana) on their wintering grounds at Aransas National Wildlife Refuge (Aransas) along the Gulf Coast. The small flock of approximately 20 birds that summered at Wood Buffalo National Park (Wood Buffalo) in Canada...
Owls
D.G. Smith, D. H. Ellis, B.A. Millsap
Beth Giron Pendleton, editor(s)
1990, Book chapter, Proceedings of the Southeast Raptor Management Symposium and Workshop.
Eight species of owls regularly occur and may breed in one or more of the southeastern states. Several additional northern or western species appear irregularly as accidentals or during years of southward incursions. In the Southeast, the most common and wide- spread owls are the common barn-owl, eastern screech-owl, great...
Selected translations of the Russian literature on the electrogeochemical sampling technique called CHIM (chastichnoe izvlechennye metallov)

1990, Open-File Report 90-462
As part of our research into new methods for the assessment of mineral deposits, the U.S. Geological Survey has recently begun investigation of the CHIM method. As part of our studies, translation of a Russian manual on the CHIM methodology and eight articles from the Russian literature were transit ted...
