Abstract We studied nestling provisioning and male song behavior associated with provisioning by Carolina Wrens (Thryothorus ludovicianus) throughout the nestling period. Overall, males and females (n  =  14 pairs) provisioned at similar rates throughout four nestling stages although males tended to provision more at the earliest nest stage (1–3 days). Males and females increased their rate of provisioning progressively over the nestling period. Parents brought one food item at a time to the… 

Female birds monitor the activity of their mates while brooding nest-bound young

These results suggest anticipatory effects generated by male behavior and that brooding females temporally map male activity to inform decisions about whether to continue brooding or to leave the nest to forage.

Vocal coordination of provisioning in Black Phoebes (Sayornis nigricans)

ABSTRACT Parent birds often vocalize near the nest to communicate with each other and their young. We observed a call made by Black Phoebes (Sayornis nigricans) as they approach the nest to feed

Predator recognition and nest defence by Carolina Wrens Thryothorus ludovicianus in urban and rural environments: does experience matter?

Carolina Wrens may have the ability to adapt their responses to local predators, both native and non-native, which may be especially important for their success in urbanized habitats.

Conspicuous calling near cryptic nests: a review of hypotheses and a field study on white‐browed scrubwrens

It is demonstrated that calling near nests could inform both adults and nestlings about the caller's behaviour, and could serve multiple functions.

The clutch size, incubation and nestling period of the Red-Whiskered Bulbul in southwest China were different from those of the P. jocosus in India, whereas, no nest building in native tropical rain forest was found.

Patterns of parental provisioning by eastern phoebes

The increasing food requirements of older or larger broods caused male and female Eastern Phoebes to increase their per-nestling feeding rates in a similar pattern and additional costs of feeding imposed by older or enlarged broods are expected to affect members of the sexes equally.

Parental investment by the Northern Mockingbird: male and female roles in feeding nestlings

Analysis of 3,293 feeding trips to nestling Northern Mockingbirds (Mimus polyglottos) in the first 11 days of nestling life showed that males and females fed young at similar rates, and males significantly increased both feeding rate and load size with age of nestlings, and their feeding rate peaked in the mid-nestling period.

PROVISIONING OF NESTLINGS BY MALE AND FEMALE YELLOW-BREASTED CHATS

The absence of any change in feeding rates with increased brood size suggests that food requirements per nestling decrease as brood size increases, perhaps because of differences in thermoregulatory costs.

Parental Provisioning in Melospiza melodia (Song Sparrows)

Offspring provisioning does appear to be truly biparental in this eastern subspecies of Song Sparrow, and increased significantly as the nestlings aged, reflecting the increased offspring feeding demands.

Sex roles, parental experience and reproductive success of eastern kingbirds,Tyrannus tyrannus

It is proposed that female site fidelity is a safeguard to avoid the lower breeding success a female would incur if she were to move to a new territory and breed with an inexperienced male, and having at least one experienced breeder substantially improved a pair's reproductive success.

NEST BUILDING IS AN INDICATOR OF PARENTAL QUALITY IN THE MONOGAMOUS NEOTROPICAL BUFF-BREASTED WREN (THRYOTHORUS LEUCOTIS)

Results suggest that effort in dormitory-nest construction was an indicator of male Buff- breasted Wren parental ability, and that by building more than females, males may increase the survival prospects of their partners.

NESTLING PROVISIONING BY THE EXTREMELY DICHROMATIC NORTHERN CARDINAL

The deflection hypothesis predicting low paternal provisioning effort in strongly dichromatic species and the assortative mating hypothesis, predicting that birds of similar quality mate with one another are rejected.

Parental Calls and Nestling Behavior in Tree Swallows

It is surprising that parents call to stimulate begging rather than wait for nestlings to beg spontaneously, but feeding visits may be more efficient if nestlings are gaping when parents arrive with food than if the parents wait for them to beg.

Why is reduced male parental assistance detrimental to the reproductive success of secondary female house wrens?

It is argued that maintenance of extensive brooding by poorly aided female wrens cannot be explained by a high risk of nestling death from hypothermia, and females in this species may stay in nests to prevent removal of offspring from nests by conspecific intruders.
