Medical and Veterinary Entomology, Volume 40, Issue 2, Page 305-322, June 2026.A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

Corvids create novel causal interventions after all [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2015 Using a novel paradigm, Tayloret al.[1] recently investigated whether NewCaledonian crows make causal interventions in comparison to 24-month-oldchildren. They view a causal intervention as the ability, after having onlyobserved a correlation between cause and effect, to produce a novel behaviouralpattern to recreate the same outcome.

Ecology and Evolution, Volume 16, Issue 5, May 2026.There is a lack of research on the predation of tropical pheasant nests. The study conducted artificial nest experiments based on egg size and we have supported the viewpoint that using experimental eggs matched in size with those of natural eggs improves the accuracy of artificial nest simulation studies. ABSTRACT Nest predation is the principal cause

Two Problems for the Political Inclusion of Animals
Journal of Applied Philosophy, Volume 43, Issue 2, Page 526-548, May 2026.ABSTRACT In recent years, the field of animal ethics has taken a political turn, with scholars arguing that sentient nonhuman animals should be included in the political sphere. This article explores two key challenges arising from this turn towards the political inclusion of animals: the Conflict Problem and the Numbers Problem.

Integumentary fibrosarcoma in a free‐living swan (Cygnus olor): Medical and welfare considerations
Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.Abstract A 10‐kg adult male mute swan (Cygnus olor) of unknown age was admitted for investigations of two large ventral masses overlying the keel bone, which were discharging purulent material. The masses measured 8.9 × 2.1 cm and 4.2 × 3.2 cm. Empirical treatment with non‐steroidal anti‐inflammatory drugs and antimicrobials was instigated.

Individual identity in songbirds: signal representations and metric learning for locating the information in complex corvid calls [PDF]
, 2016 Bird calls range from simple tones to rich dynamic multi-harmonic structures. The more complex calls are very poorly understood at present, such as those of the scientifically important corvid family (jackdaws, crows, ravens, etc.).
