Comparative Ilithology: The Study of Birth and Parturitional Behaviors Across Species
Birth is one of the most important life history events for eutherian mammals, yet it also remains one of the least understood. Perhaps surprisingly, there is no systematic field of research focused on birth and parturition through a comparative lens. In this paper, we introduce the field of…

Virtual Reality in Free-Flying Honey Bees: A Replication of Abramson et al. (1996)
In two previous experiments, Abramson and colleagues (1996) used a mirage device to demonstrate that honey bees could be influenced by a virtual reality illusion. The current study sought to replicate several key findings of their second experiment by simultaneously presenting honey bees with both…

Specialized for the Reach: Visual Control of Fruit Picking and Positional Behavior Favor a Reach Over a Grasp Phenotype for Geoffroy's Spider Monkey (Ateles geoffroyi)
The Geoffroy’s spider monkey (Ateles geoffroyi) has distinctive features, including a vestigial external thumb, elongated fingers and forelimbs, and a prehensile tail. The purpose of the present study was to understand how this derived morphology influences visually mediated reach and grasp…

Do Great Apes Know Each Other's Names? Probing Great Ape Comprehension of Social Vocal Labels
Humans use proper names as vocal labels to identify and communicate with and about social agents. The comprehension of spoken proper names requires the ability to interpret socially specific verbal signals, or social vocal labels, and use cross-modal perception to identify and discriminate between…

Why Don't All Animals Use Tools?
Tools give humans superpowers, so why don’t all animals use them? Though technology is ubiquitous in our own species, we remain unable to predict when, why, and among whom tool use will arise elsewhere in the animal kingdom. Recent decades’ research by biologists, ethologists, and archaeologists…

Behavioral Development in Beluga Whale (Delphinapterus leucas) and Pacific White-Sided Dolphin (Aethalodelphis obliquidens) Calves at the Shedd Aquarium
Knowledge of Odontocete developmental patterns is important for general comparative understanding and the implementation of informed husbandry policies. Although beluga whale (Delphinapterus leucas) calf behavioral development has previously been assessed in the literature, no previous studies have…

Difficulties in the Learning of Same-Different Discrimination Using Multiple-Item Displays in Pigeons (Columba livia)
The biological origin of the same-different concept has been extensively studied especially with pigeons, and attention and memory may be key factors in further understanding the mechanisms supporting the same-different concept formation. The primary goal of the present study was to investigate how…

The Exclusive Use of a Reach versus a Grasp When Foraging by the Mantled Howler Monkey (Alouatta palliata)
Howler monkeys (Alouatta) are characterized as energy minimizers, featuring a reduced daily foraging range, an above-branch quadrupedal positional repertoire and a reduced forelimb motion. The present study quantifies how these behavioral features influence the reach and grasp of the mantled howler…

Operant Discrimination Of Emotional Calls In Rats: Are There Biological Constraints?
Rats emit 50 kHz ultrasonic vocalizations (USVs) in positive contexts, while they produce 22 kHz USVs in negative contexts. 50 kHz USVs are possibly associated with positive affective states, while 22 kHz USVs with those of negative, and such associations may influence the feasibility of…

Gibbons (Hylobates spp.) Show Increased Attention to Eyes When Viewing Conspecific Faces: An Eye-Tracking Study
For humans, the face is a socially important visual stimulus, and the evolution of face perception has received considerable attention in research on non-human primates. However, little is known about face perception in gibbons, a key phylogenetic group among apes and humans. To address this gap…

Opportunistic Evidence of the Impact of Bacterial Infections on Social Integration in Vampire Bats
Social integration can affect an individual’s susceptibility to infectious disease. Conversely, infectious disease can reduce an individual’s social activity. Yet, it remains unclear to what extent short-term infections can inhibit social integration and the formation of new relationships. During a…

What is Rescue Anyways? A Comprehensive Review of Rescue and Rescue Adjacent Behavior Across Taxa
The term “rescue behavior” refers to a special form of altruism in which an individual aids another individual currently in distress or danger, with no obvious direct benefit to itself. In this review, we develop a modified version of Nowbahari and Hollis’ (2010) rescue criteria to classify the…

Risk vs. Reward: A Systematic Review on the Threat Faced by Mobbers
This systematic review uses a Population, Intervention, Comparison, Outcome, and Study type (PICOS) framework to identify papers on mobbing behavior in the family Paridae, comparing non-threat, low-threat, and high-threat stimulus presentations. Using the family Paridae, we discuss how using a…

Gaping in Humpback Whales, A Unique Behavior Documented Through Citizen Science
Humpback whales (Megaptera novaeangliae) are arguably the most frequently observed whale species in the world. Their coastal habits, tolerance of boats, and rapid recovery post-whaling has resulted in this species dominating whale-watching vessel operations and in-water swim-with tourism in all…

Can Physical Closeness Measure Variation and Change in Pair Association Strength in Captive Geckos?
Pair bonding is a key social behavior but remains understudied in reptiles despite a growing body of evidence suggesting that some species exhibit complex sociality. The lack of evidence regarding the expression of pair association in social lizard species hampers our understanding of its effects…

Sex and Order of Presentation Influence the Decoy Effect in Shoal Size Preference Task in Adult Zebrafish
The decoy effect is a cognitive bias where the introduction of an inferior third option shifts relative preference between two alternatives. Such biases influence foraging, mate choice, and social interactions across species. We investigated whether adult zebrafish (Danio rerio) exhibit the decoy…

A Comparative Perspective on Attentional Bias Toward Social Threat
For group-living species, including humans and nonhuman primates, the ability to navigate social encounters and quickly process threats from others is a critical skill. Rapid detection of threatening stimuli, referred to as an attentional bias toward threat, is adaptive in that fast threat…

Engineers and Architects: Shelter Construction by Male Visayan Warty Pigs (Sus cebifrons negrinus) in Negros Island, Philippines
Shelter construction has been observed in many fauna but is most common in birds, mammals and insects. Whilst nest construction for birthing and rearing young has been observed in the Eurasian wild boar (Sus scrofa) and captive Visayan warty pigs (Sus cebifrons negrinus), non-nest structures are…

Case Studies of Bear Cub Development Under Unique Rearing Conditions
Zoo-based polar bear (Ursus maritimus) literature is heavily biased towards reproduction and neonate development, or the behavioral management of adult individuals, often excluding the critical juvenile developmental period between den emergence and adulthood. The birth of two female cubs (Astra…

Fusion of Communities, the Response of Estuarine Bottlenose Dolphins to Population Decline in the Gulf of Guayaquil, Ecuador
Changes in the social structure of two neighboring communities of estuarine bottlenose dolphins in Ecuador were assessed over 14 years (2011–2024). During this period, 632 surveys were conducted, covering a cumulative distance of 23,171 km. A total of 133 distinct individuals, representing all age…
