| Swallows of the north temperate zone display a wide variety of territorial behaviour during the breeding season, but as soon as breeding is over, they all appear to adopt a pattern of independent diurnal foraging interleaved with aggregation every night in dense roosts. Swallows generally migrate during the day, feeding on the wing. On many stretches of their annual journeys, their migrations can thus be seen as the simple spatial translation of nocturnal roost sites with foraging routes straightening out to connect them. However, swallows that must make long journeys over ecological barriers clearly fly at night as well as in the day, and many suggestions indicate that there is considerable complexity in the altitude and bearing of flights even during the... |

| 北海道帯広市において森林性鳥獣類による樹洞の利用実態を明らかにするために,利用種および利用数の季節変化を,一年を通して日中と夜間に調査した.樹洞の一次生産者であるキツツキ類3種と,二次利用者である鳥類および哺乳類12種が確認された.樹洞は,日中,夜間ともほぼ一年を通して利用され,利用率が最も高い時期は日中で6月,夜間で7月であったが,利用率の季節変化は日中と夜間で同調していた.二次利用者鳥類による利用は繁殖期(夏)に多く,アカゲラ,コアカゲラ,ゴジュウカラおよびエゾモモンガによる利用は一年を通してみられた.繁殖のためだけでなく,ねぐらや休息のために樹洞を利用する種もみられ,樹洞は多様な鳥獣類によってさまざまな用途で利用されていた. |

| The Neotropical palm swift, Tachornis squamata Cassin, 1853 (Apodidae), inhabits palm forests in the northern, northeastern and central regions of South America. At the Chapada do Apodi, Brazilian Caatinga, we investigated how the Neotropical palm swifts use palm trees to roost in two areas: urban and exurban. From May to November 2011 and from March to June 2012, out of the breeding season of the species, we compared the differences between the descriptive parameters of the palm-roosts and the activity levels of the swifts in urban and exurban roosting. We sampled 30 carnauba palm-roosts in exurban areas and 32 carnauba palm-roosts and 26 Chinese fan palm-roosts in urban areas for a period of 132 days, a total of 528 hours of sampling. The number of wasp... |

| In this study carried out in the Biological Reserve of Poço das Antas, Rio de Janeiro state, southeastern Brazil, a roost of Molossus rufus (E. Geoffroy, 1805) was sampled one night per month, from November 2000 to October, 2001. The colonies in this species can exceed more than five hundreds, being present both sexes. The total number of animals captured was higher in the spring and declined in the autumn and winter. Between April to July the proportion of males overcome the females, while in other months the females prevailed. Molossus rufus have seasonal reproduction. Females arrived by July and the number increases until November. Few animals remained in this roost during colder months. Such fact suggests that females and great part of the males leave... |

| Abstract: Thyropteridae is a family of bats endemic to the Neotropical region, and Thyroptera devivoi is the only species in the family that occurs exclusively in forest patches within savannas of northern South America and north of the Brazilian Cerrado. Primary data on the species are still scarce. Therefore, in this study our objective was to fill knowledge gaps on geographical distribution, roost-use, and echolocation for the species. We observed a T. devivoi colony of 15 individuals living under a dead palm leaf. The bats used the leaf as a roost for at least four days. After capturing one individual, we confirmed the species identification via skull size and the oblong shape of the adhesive disk. The new record reinforces the association of this... |
