SummaryTwo models predicting the temporal patterns of parental investment in offspring defense over the nesting cycle were tested. The first is based on offspring age, the other on the vulnerability of offspring to predation. Both models make very similar predictions for altricial species after eggs have hatched, i.e., increases in intensity of parental defense until fledging. For precocial species, however, the post-hatching predictions of each model are different: the offspring age model… 

Effect of predator type, season, brood size, and West Nile Virus infection on the nest defense behavior of male and female Eastern Bluebirds

The effect of adult sex, brood size, stage of the breeding season, predator type, and infection with West Nile Virus on the nest defense behavior of male and female Eastern Bluebirds (Sialia sialis) was determined.

Defending the Weak: Parental Defense Peaks When Chick Vulnerability is Greatest in the Herring Gull (Larus argentatus)

It is shown that parents are most defensive when chicks are most vulnerable and that adults optimize nest defense behaviors in a way that maximizes their fitness.

The effect of offspring value on variation of nest defense intensity in gray catbirds (Dumetella carolinensis)

Variation in nest defense of gray catbirds in relation to offspring value was studied and it was found that adult catbirds defended nests that were produced earlier in the year more aggressively than later nests.

Factors affecting individual variation in nest- defense intensity in colonially breeding Black- tailed Gulls (Larus crassirostris)

The physiological state of parent birds combined with the value of their clutch may affect the intensity of their nest defense. In colonially breeding birds, nest-defense intensity may also be

Risk-taking by female ducks: intra- and interspecific tests of nest defense theory

It is found that as incubation progressed, females allowed observers to approach more closely before flushing from the nest, consistent with nest defense theory.

Experimental Study of the Effect of Clutch Size on Nest Defense Intensity in Black-Tailed Gulls

Opportunities for future reproduction, or constant individual levels of aggressiveness of seem to best explain the observed intensity of nest defense in these long-lived Black-tailed Gulls, rather than the value of the current clutch.

Sexual differences in risk-taking behaviour of the Southern house wren during the nestling rearing stage

Sexual differences detected in Southern house wrens reflect the higher ability of females to cope with the nestling needs and its lower lifetime expectancy, and that males and females delayed parental visits when exposed to the predator model.

Nesting Stage and Nest Defense by Common Terns

The temporal pattern of mobbing in the semi-precocial Common Tern most closely resembles that predicted for species with altricial young, however, interpretation is complicated by the fact that gulls prey more frequently on chicks than eggs.

Deceiving predators: linking distraction behavior with nest survival in a ground-nesting bird

This study quantified the intensity of defensive behavior of adult plovers in response to nest disturbance caused by an approaching researcher, and highlights that increased risk assumption in offspring defense is advantageous in terms of individual fitness.


Nest defense strategies can be temporally changed primarily according to the nest volume with the auxiliary agents mostly a reduction of offspring number, which indicates parental capacities and offspring conditions could shape strongly their own nest defense strategies.




To assess advantages of bi-parental care for a species with precocial young, time budgets for adult behavior with both parents and only 1 adult tending the brood are contrasted and hypotheses for strategies of parental care in this species are suggested.

Anti-Predator Aggression in Birds Nesting in Old Field Habitats: An Experimental Analysis

of elaborate, cryptic, or concealed nests, distraction displays, and nest guarding (Simmons 1955, Ricklefs 1969, Slack 1976, Scott 1977). There is evidence, although anecdotal, that some species will

The Defence of First and Second Broods by Great Tit (Parus major) Parents: A Test of Predictive Sociobiology1

The sex difference, being prevalent in 1st broods and abating in 2nd broods, indicates that the male, by its defence behaviour, not only invests in its offspring but also in its home range and/or its mate.

Risks and Rewards of Nest Defence by Parent Birds

A comprehensive functional theory of nest defence based on life-history theory can help to elucidate many of the patterns observed in this important aspect of the parental care behavior of a wide variety of animals.

Reproductive value and appropriateness of response to predators by White-Crowned Sparrows

It was found that the snake was responded to the most when the pair had nestlings, very little when the female was brooding eggs, and at a moderate level with fledglings, while the junco model elicited little response.

Variability in the Responses of Black-Billed Magpies To Natural Predators

It is suggested that although parental investment theory may be basically correct in predicting that young increase in value to their parent as they approach independence, a variety of other factors may affect anti-predator behavior, such as the types of predators likely to be encountered and the relative danger they pose to different age classes.

Social organization in a nesting population of eastern willets (Catoptrophorus semipalmatus)

Several features of the Willet social system resemble characteristics typical of colonial species of birds, and these are discussed along with other aspects of social organization and the selective forces operating on it.
