The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

Biological Reviews, Volume 101, Issue 3, Page 1235-1254, June 2026.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Friends Aren’t Food: Pinyon Jays (Gymnorhinus cyanocephalus) Show Context-Dependent Quantity Preference [PDF]

Animal Behavior and Cognition
Animals must often choose between different quantities of objects in their environment, from food items to conspecifics. Yet we know little about how quantitative cognitive abilities compare across different types of objects.

Provision of supplementary food for wild birds may increase the risk of local nest predation [PDF]

, 2017
In countries such as the UK, USA and Australia, approximately half of households provide supplementary food for wild birds, making this the public’s most common form of active engagement with nature.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Alternative behavioral measures of postconflict affiliation [PDF]

, 2012
Animals are known to affiliate after conflicts rather than avoid each other. Affiliation can occur between former opponents or between a former opponent and a third-party, and is more common between individuals with high-quality relationships.

Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change

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 ...

The Larger the Egg, the Safer the Nest: A Study on the Negative Correlation Between Nest Predation Rates and Egg Size of Two Tropical Phasianids in Hainan

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

Testing nest deterrents for Chihuahuan ravens on H‐frame transmission structures

Wildlife Society Bulletin, 2015
Chihuahuan ravens (Corvus cryptoleucus) regularly perch and nest on electric utility structures. Because ravens perch on overhead shield wires, for which no perch discourager exists, management focuses on nests.
