Adult female brown long-eared bats, Plecotus aurituswere taken into captivity over a 3-year period and housed in two free-flight enclosures. They were maintained in small groups, each roosting in a single, heated roost box while monitored by an infra-red sensitive video camera. The predicted percentage of records spent by lactating females in direct contact with the young on day 1 of lactation did not differ significantly from 100%. This declined to 13% on day 50 of lactation. Over time, the mothers groomed the young less. Lactating females visited the roost more times per night, but spent less time self grooming than non-reproductive females. The total amount of grooming behaviour (estimated as the percentage of records spent in self grooming plus those allocated to grooming of the young) for lactating females was 50% of the value for non-reproductive females. In general, care-giving behaviours declined with the progress of lactation. The temporal expression of these behaviours was opposite in direction to that of the expected energetic demands of milk production.Copyright 1997 The Association for the Study of Animal Behaviour1997The Association for the Study of Animal Behaviour
成年雌性棕长耳蝠（Plecotus auritus）在3年的时间里被圈养，并安置在两个自由飞行的围栏中。它们被分成小群体饲养，每个群体栖息在一个单独的加热栖息箱中，同时由一台红外敏感摄像机进行监测。哺乳期雌性在哺乳期第1天与幼崽直接接触的记录预测百分比与100%没有显著差异。到哺乳期第50天时，这一比例下降到了13%。随着时间的推移，母亲对幼崽的梳理次数减少。哺乳期雌性每晚访问栖息箱的次数更多，但用于自我梳理的时间比非繁殖期雌性少。哺乳期雌性的梳理行为总量（估计为自我梳理记录的百分比加上用于梳理幼崽的记录百分比）是非繁殖期雌性的50%。总体而言，照顾行为随着哺乳期的推进而减少。这些行为的时间表达方向与产奶预期能量需求的方向相反。版权所有1997动物行为研究协会1997动物行为研究协会
