Conclusion and Clinical Relevance--At the doses tested, buprenorphine hydrochloride resulted in thermal antinociception in American kestrels for at least 6 hours, which suggested that buprenorphine has analgesic effects in this species.
In American Kestrels for which brood sizes had been experimentally manipulated, growth rates (mass) of females in larger broods were lower than those in control or reduced broods, and ninth primary length in young from enlarged broods was smaller than that in young from smaller broods; however, tarsus length did not differ among brood sizes (Gard and Bird 1992).
