We reporr here on aspectsof the development of bird-bome PTTSand some of the past and presdt applications of satellite tracking to study avian speies. The use of satellite tracking to locate ud forRast bird movemenrs and migration ro aid in the bild strike probtem has been proposed (Lshem 1990). A satellite kacking system used with other emerging tehnologies and capabilfties to addrcss rhe bird stdke problem is discussed. Conventional Telemetry system Technologi€s Biotelemetry lus dramatically iilluenced the direction of w dlife resear.h since the first application by Southem (1964)to srudy the wintering behavior of bald eagles Glaliaeetus leucacephaluE. The use of conventional telemeky has allowed for a more fto-.ough .apability to pe orm basic researchand examine ecological and management issuesrclated to dimal behavio!, survivat, productivity, migation and habitat use. Biotelemetry has been especiajly helpfut in the study of avian speciesbecausebirds often are widely dispersed adoss the lands.ape md use targe areasthrough which they can move quickly. l-cally bird! can make diumal or nocturnal movements b€tween forging deas and roostinS sites while seasonally they can rravel geat disranc€sberween breeding, migratory and wintqing habitats. Conventional telemetry is como.ty enp:oyed to locate birds to obene behavior and gather informarion on rheir range ed patterns of habitat use. This information can be collected by severat methods, the most comon by homing toward the Edio signal or triangllation pe ormed by d€riving a directioml bearing on the tagged animal from two or more reeiver positions with a directional antenna. In nearly all appticatioro of conv€ntional biotelemetry, it is restri.ted to local use with animal pos ions being collecred on fooL frcm automobiles or small fixed wins aircraft. A pplicatioroor biot€lemebyhaveb"en successiu I in developing management plans for the coroeNation of avian species. Bloom er. al (1993) determined by meais of biotelemetry that red,shouldered hawks coutd e6ily be !11aru8€d withhul)Machvity inareash SourhernCJifomia due to rheirhme range or 1.2 sq@e kilometer in seleted woodland habitat. Hauq dd Olifmr (l990)dnd Mdersky andSnyde.(1992)Londucringradio tetemeriystud,esatso were able to make coreenation recomendations for burrowing owb fAthene gelisela:gal and California.ondors (Gynnogyps califonianus) in their oM udque habitats. Condors posed more difficllt study problems becauserhey ranged over 200 kilometers during forging flights from rheir nest or roost. rn this study conventional telemetry was used to supplement obsenarioro to assistin evaruadng the bnds behaviors and colect injured or dead individuats. Shenod et. al (1981)sinilarly used biotelemerry to examine the releaseof caprive bred 444 peregdnefalcons in order to re-establish the spei$ in deas from which rhey wercprcviously extirpated due to pesticide use. SmaI tail mounred bansmitters wereused to hack peregdnes to examine their behavior, adapration ro the wild state,6nd determine the causesa late oI mortaliry. Biotelemeky also has be€n used to asse$ effects of Iand us€ activities on avianspecies. Buehler €t. al (1991)and Anderson €t. al (1990)used radio t€lemetryto €valute raptor behavior in regard to material tesr and evaluarion aclivitis on military lands. S€egd dd Fuller have co"mmg€d a emprehensive progam to study raptors in relation to military rraining in the SnakeRiver Bird6 of Prey Narional Conserative Area (SRBOpNCA), (Marztuff e( aL 19yJ). Biotelemeky was used on 120 pralie falcoro (Falco nexicanus) duringfou breedings€asoreto exmine their distribution and evdluarethe elfectsof military training on their biology. Lcation esrinutes were collected andcorElated to real-time military training, v€getatiorr ground cover, prey dishibution and other geogiaphically significat variables. Home range and talconactivity .d be evaluated in rcgard to thesepardeters. Land use panehs oI the local population of prairie falcons derived ftom the iandom telemeky samplealsowere eemired usinga splinedsubrourin€in ArcllnloSortua;e {ArlInJo, Envirommtat SystemsResearchInstirut€ Inc., Redlands, California). Thisapproach was used to produce a contour map of prairie falcon sparial use of thestudy ar€a. The CeoSraphic Inlomation System (cls) we developed embtes u, to identiJy areasof high and low us€ by falcons, dd to relale them ro land-use pattemsand management options. lMovations in biotdemetrr' systernshave led to th€ developmenr of s€Mrs ed sp€cial-pupose transmitters to .oll€.t an array of inJomation. The measurementsof movement ud temperature are the most corunonly used tensorsin wildlife studis (Kenward 1987:61).Motion sensorccan be modified to log activity over time thus identifying periods of prolonged acrivity and inactivity or nortality (Kenwdd 1987). Sensorshave ban tlsed to detect attitude (Bogeland Burchard 1992),humidity (Howey et al.19Z, gasrric morility (Ku€clrleet al. 1984 and hearr rate (sawby and cessM 1924).Sladen and Cochre develop€d an auromatic tracking starion to detect the Fesence of telemetrysignals fiom transmitters atrached to tundra swm, (Cygnus columbianuscotumbianus) staging for sp ng migration from the Chesapete Bay,lvkryland and Virginia. The system was designed to alam biologists when signalswere detected flom swans moving north from rheir wintering areas. Resulti fiom this work provided valuabte inlormarion on the hamess atrachmenr of back?ack transmitters as wel as temporal and spatiat inJounation on the swai's' spring migration (Sladenet al 1969,Sladen and Cochra& 1969md Sladen 1974).Individualy cod€d transmitters have been developed in order to in reas€ thenumber of bansmifters Lhatcan be monibored in rhe field.

Howeve!, the use of aircrafr is eapensiveand not pra.tical fo! tracking long distance migrants thaf rravel thousands of miles, cross .lozens of gcopolitical boundaries and travclse remote regions of thc globe. Limiting fa.tors associatedwith convcntional telemeby such as restri.ted geographic range and huhan operarion requircd to obtain inlormation on ftee ranging animls prompted the development of spacedbasesystemsto rrack and moniior wildlife via satellite.

Bird borne PTIS becamea reality for kacking and monitoring activities of avi.I specis in 1984when this sotar powered PTT was su..ssfulty fielded on dEbaclof a wild nute swan (cygnus olor) captured in fte chesapeake Bay of I,tiryland(Strikwerda et al. 1984). Sincethen the tehnology has continued to dd provide a unique capability to track and monitot avian sp€cies develop $'€ighing as litde as 800 grns. The next field test conducted with the Johs Hoplitr University PTI was in 1984on a sub-adutt bald eagle. This mptor was backedfor 270 days over a 2400 kilom€ter range from Maryland to Florida. The !e$lt! of this experiment led to a seriesof field tests of the technology with other aviansFcies (Strickwerda et. al, 1986)- Additiomt {ield testswere conducted on baldeagleegolden eaglesand a gy alcon as the PTT was redu.ed in size from 185gm to a 95 gm unit produced by Microwave T€lemetry Inc. (Hovr'ey, 1989). Applicetions Eagleg As the technology contirued to develop and b(ome available, others usedIfis to track and monitor the griffin vulture (Gdesigner et. al, 1992),Lesser rpottedeagles(Meyburg et. al, 1993)and a Steller's seaeagle (Meyburg and lobkov, 1994). Satellite backing is now b€ing us€d to do basic rcsearch on many avianspeciesfor conservation and resource nunagement plaming. In Gla.ier BayNational Park the *6oGl movements of bald eagles,wer€ eramined by srtelliie hacking to study the eaglesforaging relationship to strearu and dvers thatpotentiauy could be aff€cted by pro?osed copper mining activities (Kralovec 1994).In Canada, Brodeau and D€Carie (1993)studied golden eaglesto evaluate theimpact of a proposed hydroel€.tric dam to be coNtrucred south of lames Ba, Ontario. Eaglesfrom the area to be flooded were tagged with Pfis and backedsouth to their wintering Founds.

On the OTA, cent ally located within the SnakeRiver Birds of Prey NationatC-onservationArea , we examined the spatial relationships of military haining to golden ea8le movements. Satetlite telemetry was used to collect lo.ation data ftom eagl€sthat frequented military exctusion areasand to detemine wintering rang€s for adult and sub-adult eagles(Seegd et al. 1996 in press).
