Krill-feeding behaviour in a chinstrap penguin compared to fish-eating in Magellanic penguins: a pilot study. [PDF]

open access: yes, 2004
Inferring feeding activities from undulations in diving depth profiles is widespread in studies of foraging marine predators. This idea, however, has rarely been tested because of practical difficulties in obtaining an independent estimate of feeding ...

The hearing capabilities of the Dromornithidae (Aves), with inferences on acoustic communication and ecology

open access: yesJournal of Anatomy, Volume 248, Issue 1, Page 82-93, January 2026.
The preservation of bony structures which enclose the hearing organs (ECD) provide a basis for interpreting the hearing capabilities of the extinct, flightless Dromornithidae (Aves). Although the length of the dromornithid ECD was especially short, relative to basicranial length, it conformed to the negative allometric scaling relationships observed in

Non‐Passerine Birds in Zoos: A Global Approach on Distribution Patterns of Threatened Birds in Zoological Institutions 动物园中非雀形目鸟类:全球动物机构中受威胁鸟类的分布模式研究

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 600-615, December 2025.
Only 1541 (34.2%) of 4503 recognized non‐passerine bird species are held in ZIMS institutions worldwide. Approximately ~83% of the species kept globally are classified as non‐threatened and ~16% as threatened. To improve the conservation of threatened birds, a shift toward keeping threatened species should be considered within ex situ management ...

ABSTRACT The New Zealand fur seal/kekeno (Arctocephalus forsteri, NZFS) is native to Aotearoa/New Zealand. Its original range included the entire coast of mainland New Zealand, and offshore and subantarctic islands. The NZFS has gradually recolonised much of its former range after being almost extirpated by hunting, however, little is known about ...
