Defence strategies of established, familiar rock pipit neighbours were studied in a population breeding at high density. Theoretical arguments suggest that an armistice and some form of cooperative defence should occur between familiar, territorial neighbours when an intruder tries to settle in an occupied area and owners risk losing part of their territories and renegotiating boundaries. Boundary displays were at a low and steady level after neighbours had been claiming their territories for 4… 
Aggression towards shared enemies by heterospecific and conspecific cichlid fish neighbours
TLDR
The results suggest that previously demonstrated higher survival of convict cichlid broods in close proximity of mogas may be driven by aggression towards shared enemies, and heterospecific neighbours may provide protective benefits in a wider range of ecological settings than commonly considered.
Effects of landmarks on territorial establishment
Abstract The period of territorial settlement is critical for territorial species, and the initial disputes to fix the boundaries can be energetically expensive. Territorial residents may be able to
The signal value of vocalisations revealing auditory threat assessment in meadow pipit males (Anthus pratensis)
TLDR
If territorial males are able to assess the extent of threat posed by con- and heterospecific intruders in an area of sympatry, they could optimise the expression of territorial behaviour by showing enhanced response to conspecific relative to heterOSpecific Soft calls.
Vocal and visual communication in territorial rock pipit males (Anthus petrosus), focused on playback experiments. A study of the information content of displays
TLDR
No single vocal component is a reliable signal leading to physical fights, but one particular, directed visual display is frequently seen before a clash and is then combined with intense vocalizations, which determine how to settle serious conflicts.
Animal behaviour: Coalition among male fiddler crabs
TLDR
It is shown that territory-owning Australian fiddler crabs will judiciously assist other crabs in defending their neighbouring territories, which supports the prediction that it is sometimes less costly to assist a familiar neighbour than to renegotiate boundaries with a new, and possibly stronger, neighbour.
Know thine enemy’s neighbor: neighbor size affects floaters’ choice of whom to fight
TLDR
A strong effect of the neighbor's size is found on whether or not a territory-seeking male initiated a fight with a resident male in the fiddler crab Uca mjoebergi.
When and Why Do Territorial Coalitions Occur? Experimental Evidence from a Fiddler Crab
TLDR
This work provides the first evidence of the rules determining when territorial coalitions form in the African fiddler crab Uca annulipes, which lives in large colonies wherein each male defends a burrow and its surrounding area against neighbors and “floaters” (burrowless males).
Conditional strategies in territorial defense: do Carolina wrens play tit-for-tat?
TLDR
Examination of the response of territory owners to playbacks of neighbors at shared boundaries before and after intrusions by that neighbor or by strangers showed that territory owners did not increase their aggression toward defecting neighbors but did increase their aggressive toward neighbors after a simulated intrusion by a stranger.
Agonistic encounters in a cricket frog (Acris crepitans) chorus: Behavioral outcomes vary with local competition and within the breeding season
TLDR
It is suggested that the most important variables impinging on a male's decision to fight, flee, or ignore an intruder are influences external to the individuals involved in the conflict.

Abstract Abstract. Many territorial animals respond less aggressively to neighbours than to strangers (the dear enemy phenomenon). The dear enemy phenomenon generally has been assumed to represent
Social Stability and Territory Acquisition in Birds
This study tested the hypothesis that one strategy birds use to acquire territories is to seek and exploit areas where conspecific social stability is weak. Predictions were that nonterritorial
Imperfect Information and the Persistence of Pretenders: Male Prairie Warblers Contesting for Territory
TLDR
A speculative explanation for an extended escalation of territorial contests among birds returning to breeding sites from their winter range may result when information about birds' respective roles is poorly known, thereby making escalation a feasible strategy even for contenders that will probably lose the escalated contests.
Polygyny and Nest Predation in the Rock Pipit Do Females Trade Male Assistance Against Safety
TLDR
Mating systems in territorial birds have been discussed in terms of female mate choice since the polygyny-threshold model appeared and the idea of free choice has been questioned; preferred options may not always be obtainable because of conflicts of interest between males and females.
Dear Enemies and the Prisoner's Dilemma: Why Should Territorial Neighbors Form Defensive Coalitions?
TLDR
Game-theoretic arguments are used to derive two new hypotheses to explain why territorial residents so consistently defeat potential usurpers, based on help from established, familiar neighbors.
