Faces have features characteristic of the identity, age and sex of an individual. In the context of social communication and social recognition in various animal species, facial information is relevant for discriminating between familiar and unfamiliar individuals. Here, we present two experiments aimed at testing the ability of cattle (Bos taurus) to visually discriminate between heads (including face views) of familiar and unfamiliar conspecifics represented as 2D images. In the first… 
Female horses spontaneously identify a photograph of their keeper, last seen six months previously
TLDR
Overall, the results show that horses have advanced human face-recognition abilities and a long-term memory of those human faces.
How dogs scan familiar and inverted faces: an eye movement study
TLDR
Facial images were generally more attractive for pet dogs than kennel dogs, but living environment did not affect conspecific preference or inversion and familiarity responses, suggesting that the basic mechanisms of face processing in dogs could be hardwired or might develop under limited exposure.
Visual discrimination of species in dogs (Canis familiaris)
TLDR
Pet dogs were successfully trained through instrumental conditioning using a clicker and food rewards to choose a rewarded image, S+, out of two images displayed on computer screens and have the capacity of species discrimination despite their great phenotypic variability.
Sheep recognize familiar and unfamiliar human faces from two-dimensional images
TLDR
Data show that sheep have advanced face-recognition abilities, comparable with those of humans and non-human primates.
Human Face Recognition in Horses: Data in Favor of a Holistic Process
TLDR
No single facial element that the authors tested appears to be essential for recognition, suggesting holistic processing in face recognition, which means horses do not base their recognition solely on an easy clue such as hair color.
Valence of Facial Cues Influences Sheep Learning in a Visual Discrimination Task
TLDR
It is suggested that sheep can perceive the emotional valence displayed on faces of conspecifics and that this valence affects learning processes.
Individual differences in facial configuration in large-billed crows
The recognition of individuals is a basic cognitive ability of social animals. A prerequisite for individual recognition is distinct characteristics that can be used to distinguish between other
Cerebral and behavioural assymetries in animal social recognition
TLDR
Evidence is here summarized that animal species belonging to distant taxa show forms of social recognition, a sophisticated cognitive ability adaptive in most social interactions, and evidence of functional lateralization for this cognitive ability is reviewed.
Social discrimination of cage-mates and non-cage-mates by rats
How visual system configuration can play a role in individual recognition: a visual modeling study
TLDR
It is found that recognition in chickens occurs at short distances due to constraints imposed by their visual system, which can affect the costs and benefits associated with social spacing in groups.

Monkeys recognize the faces of group mates in photographs
TLDR
It is demonstrated that capuchin monkeys, like humans, recognize whom they see in a picture, and facial identification based on real-life experience with the depicted individuals is suggested.

TLDR
These studies indicate that non-human primates carry out the visual analysis of complex images such as faces in a characteristic and quantifiable manner.
