Effects of human approaches to nests of northern New Zealand dotterels
Fine-scale three-dimensional spatial use by diving, lactating female Weddell seals Leptonychotes weddellii
Despite the importance of fine-scale spatial use in understanding an animal's foraging ecology, these data cannot readily be collected for free-ranging marine mammals. We used an acoustic positioning…

An unexpected pattern of molecular divergence within the blue penguin (Eudyptula minor) complex
Evidence for 2 unexpected clades is found: the 1st consisting of Otago and Australian populations, the 2nd consisting of north- ern, Cook Strait, Chatham Island, and Banks Peninsula populations, some support for these 2 clades was found from a re-analysis of morphometric data and from a preliminary examination of vocalisations.

Low cost displays are more effective because they reveal a willingness to take risks and also place the opponent in a higher risk situation than high cost displays that are accompanied by calls.
‘O sibling, where art thou?’‐ a review of avian sibling recognition with respect to the mammalian literature
The reason why avian work is rare, how approaches differ and what avian and mammalian researchers can learn from each other are identified are identified.
