The Florida scrub jay : demography of a cooperative-breeding bird
TLDR
It is found that habitat restraints, rather than kin selection, are the main source of the behavior of Florida Scrub Jays: the goal of increasing the number of close relatives other than descendants in future generations is of relatively minor importance in their cooperative-breeding behavior.

The Inheritance of Territory in Group-Breeding Birds
TLDR
It is hypothesized in this paper that, in certain species, remaining home and helping represents a strategy used by nonbreeders to inherit the space necessary for breeding.

Multi-locus DNA fingerprinting supports genetic monogamy in Florida scrub-jays
TLDR
In Florida scrub-jays, large territory size may limit opportunities for cuckoldry, and persistent intense competition for limited breeding space may lead to low variance in the quality of established male breeders, which would reduce both the opportunity for, and benefits of engaging in extra-pair fertilisations.

ACORN HARVESTING BY FLORIDA SCRUB JAYS
TLDR
Use of a habitat characterized by relatively large and dependable annual acorn crops that are evenly dispersed, coupled with caching behavior, may contribute to the maintenance of permanent territoriality and co- operative breeding in this population of Scrub Jays.

Consequences of heterogeneity in survival probability in a population of Florida scrub-jays.
TLDR
It is shown that survival probabilities are structured by age, birth cohort, and maternal family, but not by sex, and substantial structured heterogeneity for survival exists in this population of Florida scrub-jays.

Prey Capture by the Brown Pelican
TLDR
For the first time, the use of the bill and pouch during prey capture by diving Brown Pelicans is described, which accurately represents the technique Brown Pelicans use when diving to catch live fish.
