This thesis examines the issue of law enforcement’s use of unmanned aerial systems (UAS) from an ethical perspective. As UAS have only recently been introduced into the National Airspace System (NAS), legislation regarding their use in America’s skies is lacking. This dearth of statutory guidelines creates a circumstance wherein self-imposed limits on UAS use by law enforcement take on greater importance. The primary research question posed by this thesis is whether a prevailing ethical framework exists to govern the use of UAS by domestic law enforcement functions. It concluded no consensus exists. Using the case study method, this thesis considered documentary evidence of ethical frameworks for UAS currently in use by law enforcement. A comparative policy analysis is then performed to identify overlapping areas of concern, in order to arrive at a template that recommends seven dimensions that law enforcement executives should consider in creating a drone-specific code of conduct for policing. A case is made for publicly declaring an agency’s code of conduct in the interest of strengthening the relationship between police and the public vis-à-vis the social contract. http://archive.org/details/ethicsonflytowar1094548476 Office of Law Enforcement, Transportation Security Administration, Chantilly, Virginia Approved for public release; distribution is unlimited.

Polioptila attenboroughi new species Inambari Gnatcatcher balan��a-rabo-do-inambari (Portuguese) Holotype.- Museu Paraense Emilio Goeldi (MPEG) 63204, skin, adult male; skull 100% ossified; no Bursa of Fabricius; left testis 4x3 mm; 6 g; little fat and no molt. Collected (shot) and tape-recorded in a mixed-species canopy flock of insectivores in upland (terra-firme) sandy-soil forest by AW on 5 July 2007 at Tupana Lodge, located at km 158 of the BR-319 road in the municipality of Careiro, Amazonas, Brazil (04�� 05' 00.2"S; 60�� 39' 37.8"W); prepared by AA and Manoel Santa-Brigida under field number TUP 010. Pectoral muscle tissue preserved in approximately 96% alcohol; field number TUP 010. Hologenetype (Chakrabarty 2010) sequences of the mitochondrial gene NADH subunit 2 (1041 bp) deposited in GenBank (accession number KC823272). Tape-recordings of vocalizations archived at the British Library of Maturai Sounds under accession number 183249 (available at http://www.bl.uk/listentonature/main.html). Diagnosis: Morphology.- Alphanumeric color designations determined through direct comparison with Smithe (1975). Both vocalizations (loudsongs and multi-note calls) and overall plumage, with males having no black on the head and possessing narrow rectrices with white on the outer three pairs but none on the three central pairs, clearly place P. attenboroughi in the P. guianensis complex. Adult males (no female specimens are available) of the new taxon are readily distinguished from males of all remaining taxa in the P. guianensis complex by decisively darker plumbeous (color # 78) upperparts, chest, and lower throat, in these respects approaching P. facilis and P. schistaceigula (Slate-throated Gnatcatcher), farther differing from the former by a thin, broken, white eye ring (nearly absent in P. facilis), and from the latter by a significantly longer tail with white on the outer feathers and lack of any white in the head (see Table 1 in SI for a list of specimens examined). From P. guianensis, it also differs by a uniform slate throat and breast (instead of having a contrastingly paler whitish throat), and three outermost rectrices with extensive black bases, rather than nearly entirely white. In comparison with recently described P. clementsi, it further differs by the greater extent of black bases on outer rectrices (covering approximately 20%, 60%, and 95% of the three outermost rectrices, respectively, in P. attenboroughi). From P. paraensis, with which the new taxon shares the tail pattern, differentiated only by a much darker slate color of the upperparts. throat, and chest. Voice.- The loudsong of P. attenboroughi is most similar to that oiP. paraensis in compri sing an evenly paced series of notes at a nearly level frequency, but pace is significantly slower and note shape (and thus, auditory quality) is subtly different. Furthermore, P. attenboroughi possesses a distinctive "rasp" series delivered in the context of a complex song that is lacking (or perhaps only very rare?) in P. paraensis but shared with P. schistaceigula (see Vocalizations, below). Genetic divergence.- Separated from its sister-species, P. paraensis, by approximately 3.9 % sequence divergence, and from the more distantly related P. schistaceigula and P. guianensis, respectively, by 14.3% and 13.6% sequence divergence in the mitochondrial gene NADH subunit 2 (see Phylogenetic relationships, below). Distribution.- West of the Madeira and south of the Solim��es rivers in the Inambari area of endemism (Silva et al. 2005) in Brazil, where presently documented from only a few localities (Whitney and Alvarez 2005, Whittaker et al. 2008; Fig. 1). Description of holotype.- See color illustration. Alphanumeric color designations determined through direct comparison with Smithe (1975). Head, nape, and mantle through uppertail coverts uniform plumbeous (color 78). White eye-ring, slightly broken at front and back edges. Throat and breast, including some posterior extension to sides, also plumbeous (lightest at the uppermost throat where a few suffused whitish feathers are found). Upper belly and posterior extension to flanks concolor with throat and chest; remaining underparts including undertail coverts white. Primaries and secondaries plumbeous (color 78), outer vanes of primaries finely edged with dark gray, inner vanes narrowly edged whitish. Alula and smaller, overlying feather blackish with thin whitish margin on outer vane; primary coverts same blackish but lacking whitish margins. Underwing coverts white. Tail unworn and distinctly graduated. Three inner pairs entirely blackish. Rectrix No. 4 mostly blackish with a white tip (about 95% blackish); No. 5 mostly blackish (ca. 60%), white towards the tip, mostly on the distal vane. Outer rectrices (pair No. 6) approximately 80% white with approximately basal 20% of proximal vanes blackish. Soft parts in life; Iris light brown/creamy; maxilla blackish gray; mandible light gray; tarsi and feet bluish gray. Standard measurements: Bill length (culmen from base at skull) 11.9 mm; bill width at anterior edge nares 3.2 mm; bill depth at anterior edge nares 2.5 mm; wing chord 46.7 mm; tail length 51.4 mm; tarsus length 12.5 mm; mass 6 g. Etymology.- The new taxon is named in honor of Sir David Frederick Attenborough who has long been a mentor to many generations of ornithologists. Sir David has become a worldwide household name with countless magnificent TV natural history programs spanning almost 60 years, which he so passionately presents and narrates. Having had the honor of working with Sir David, one of us (AW) witnessed firsthand his endless passion and appreciation for nature. Sir David is best known for writing and presenting the nine Life Series with the BBC Natural History Unit, which collectively form a comprehensive survey of all life on our planet. He has succeeded like nobody else in captivating countless millions of television spectators worldwide, enabling them to appreciate and enjoy nature for the first time, and clearly highlighting the major perils facing our magnificent planet earth and its wildlife. Sir David has done an outstanding job documenting important current topics such as global warming and the alarming numbers of species that humans are driving towards extinction, and confirming the essential need for us to do a much better job of conserving our planet's precious nature for future generations to enjoy. The English and Portuguese names reference the center of endemism to which Polioptila attenboroughi is restricted. REMARKS Type series.- Paratypes of P. attenboroughi are the following two specimens: MPEG 63203: skin, adult male, left testis 6x4 mm, no molt, collected (shot) in the canopy of upland {terra firme) sandy-soil forest by AA on 4 July 2007 at the type locality and prepared by AA and Manoel Santa-Brigida under field number TUP 003. Tissue samples deposited at MPEG under field number TUP 003. Mitochondrial gene NADH subunit 2 sequences deposited in GenBank (KC823273). Recordings of vocalizations archived at British Library of Natural Sounds under accession number 183249 (available at http://www.bl.uk/listentonature/main.html).INPA 2233: skin, adult male, left testis 6 x 5 mm, trace molt, no Bursa, skull 100% ossified, collected (shot) in the canopy of upland (terra firme) forest by Mario Cohn-Haft on 18 July 2007 at "Campo da Catuquira", ca. 240 km south of Manaus, Amazonas, Brazil (04�� 55' S; 61�� 07' W) and ca. 100 km to the southeast of the type locality in the Madeira-Purus interfluve;specimen prepared by Mario Cohn-Haft and Ingrid Macedo under field number MCH 665. Tissue samples deposited at INPA under number A-1397; not sequenced. Recordings of vocalizations archived at the Macaulay Library of Natural Sounds under accession number 169991. Variation in the type series: The type series includes three specimens, all males. The only apparent slight variation pertains to the iris color, which is recorded as light-brown/creamy in the holotype, light orange-brown in MPEG 63203, and dark brown in INPA 2233. Whether this represents a true type of variation or just subjectively distinct transcriptions of iris colors cannot be properly assessed at this time given such a small series of specimens. Nevertheless, widely distinct iris colors have also been recorded within series of specimens of other taxa in the P. girianensis complex (Whitney and Alvarez 2005; see also Table 1 in SI for a list of specimens examined), suggesting that at least some individual variation is involved. Ecology and behavior.- Polioptila attenboroughi. like other members of the P. guianensis complex, forages alone or in pairs in the canopy of upland (terra firme) sandy-soil forest, apparently exclusively in association with mixed-species canopy flocks. While foraging, it usually gleans prey off the surface of leaves and twigs, mainly in dense terminal branches, while in fast motion and with its tail cocked and flicked laterally, and rectrices sometimes spread. It can also chase flushed prey into the air by "jumping" and flying short distances, quickly returning to tree branches. So far, apparently no records outside tall, upland sandy-soil forest exist, so the species seems tied to this patchily distributed habitat in western Amazonia. Due to its weak, highpitched voice, and overall low density, it is easily overlooked. The nest and eggs remain unknown. Vocalizations.- Figure 2 enables comparison of characteristic vocalizations of Polioptila attenboroughi with pertinent, homologous vocalizations of other members of the overall P. schistaceigula complex, complementing data anr 1 spectrograms presented at equivalent scales by Whitney and Alvarez (2005; their figure 3). Typical vocalizations of these taxa, including those used to make the spectrograms in Figure 2, are available for listening on the IBC website. As expected, among comparisons of all taxa, the loudsong of P. attenboroughi (n = 4) most resembles that of its sister-species, P. paraensis, but an attentive listener will discern distinctions in pace (number of notes per second, perceptibly slower in P. attenboroughi P, Published as part of Whittacker, Andrew, Aleixo, Alexandre, Smith, Brian T. & Klicka, J., 2013, A distinctive new species of gnatcatcher in the Polioptila guianensis complex (Aves, Polioptilidae) from western Amazonian Brazil, pp. 301-305 in Handbook of the Birds of the Wold Special volume: new species and global index, Barcelona :Lynx Edicions on pages 301-304, DOI: 10.5281/zenodo.15074
