| suspected anaphylaxis to leuprolide acetate depot in two elf owls (micrathene whitneyi). | two adult female elf owls (micrathene whitneyi) were treated with leuprolide acetate depot injections to prevent egg laying. the birds were treated for several years without complications. several years into the treatment regimen, both birds died immediately after receiving an injection of leuprolide acetate. remaining drug was analyzed, revealing 95.7% potency. we suspect that either an immediate type 1 hypersensitivity reaction occurred or a contaminant was present, resulting in the fatalities ... | 2011 | 22946393 |
| avian thermoregulation in the heat: metabolism, evaporative cooling and gular flutter in two small owls. | the thermoregulatory responses of owls to heat stress have been the subject of few studies. although nocturnality buffers desert-dwelling owls from significant heat stress during activity, roost sites in tree and cactus cavities or in deep shade provide only limited refuge from high environmental temperatures during the day. we measured thermoregulatory responses to acute heat stress in two species of small owls, the elf owl (micrathene whitneyi) and the western screech-owl (megascops kennicotti ... | 2018 | 29925545 |
