Abstract

While banding ferruginous pygmy-owls (Glaucidium brasilianum) and Eastern screech-owls (Megascops asio) in south Texas during 2004, we recorded Philornis mimicola (Diptera: Muscidae) and Ornithodoros concanensis (Acari: Argasidae) parasitizing nestlings. Inspection of nestlings revealed 54 P. mimicola and one O. concanensis. Inspection of nest material revealed 111 P. mimicola, including 57 puparia. The effect (e.g., blood loss, anemia) of these hematophagous parasites might have contributed to the demise of at least one Eastern screech-owl nestling. This is the first record of P. mimicola and O. concanensis parasitizing ferruginous pygmy-owls and Eastern screech-owls.

摘要

2004年在得克萨斯州南部对棕鸺鸮（Glaucidium brasilianum）和东美角鸮（Megascops asio）进行环志时，我们记录到了寄生在雏鸟身上的拟嗜鸟蝇（Philornis mimicola，双翅目：蝇科）和康卡纳钝缘蜱（Ornithodoros concanensis，蜱螨亚纲：argasidae科）。对雏鸟的检查发现了54只拟嗜鸟蝇和1只康卡纳钝缘蜱。对巢材的检查发现了111只拟嗜鸟蝇，其中包括57只蛹。这些吸血寄生虫的影响（如失血、贫血）可能导致至少一只东美角鸮雏鸟死亡。这是拟嗜鸟蝇和康卡纳钝缘蜱寄生棕鸺鸮和东美角鸮的首次记录。
