Fledgling Peruvian Pelicans (Pelecanus thagus) Attack and Consume Younger Unrelated Conspecifics

  title={Fledgling Peruvian Pelicans (Pelecanus thagus) Attack and Consume Younger Unrelated Conspecifics},
  author={Maximiliano Daigre and Paulina Arce and Alejandro Simeone},
Abstract Aggression between chicks and fledglings, at times ending in siblicide and cannibalism, has been mostly studied among nest mates. It is frequent among colonial-nesting birds and is usually related to competition for limiting resources (e.g., food and space) and competitive disparities between siblings, among other factors. We report three observations of full-grown Peruvian Pelican (Pelecanus thagus) fledglings attacking unrelated conspecific nestlings at a breeding colony in central… 
Indirect Cannibalism by Crèche-aged American White Pelican ( Pelecanus erythrorhynchos ) Chicks
Cannibalism in the American White Pelican appears to be rare and likely plays no role in the species’ population ecology or dynamics; however, it might be an important survival strategy of individual chicks when food resources are limited.
Cannibalism by Brown Booby (Sula leucogaster) at a small tropical archipelago
Brown Booby cannibalism is reported at Saint Peter and Saint Paul Archipelago, offshore Brazil, and possible causes such as opportunistic feeding, colony sanitation and space competition for nesting places are discussed.
Cannibalism in southern giant petrels (Macronectes giganteus) at Nelson Island, Maritime Antarctic Peninsula
This study describes two cases of cannibalism in a population of southern giant petrels breeding at Harmony Point (62°18′S; 59°10′W), Nelson Island, and confirms that heterocannibalism is part of the behavior repertoire of male southern giantPetrels.
Presence of the Peruvian Pelican Pelicanus thagus in seabird colonies of Chilean Patagonia
The coast of the Los Lagos region (40–44°S), in Chile, forms an intermediate biogeographic zone that sits between the Humboldt Current and the Sub-Antarctic Current systems, where there is a mixture
A bird-eye view on the spatio-temporal variability of the seasonal cycle in the Northern Humboldt Current System: the case of Guanay cormorant, Peruvian booby and Peruvian pelican
In the Northern Humboldt Current System, the seasonality of breeding is more influenced by local environmental conditions than by large-scale environmental gradients, which provides critical information to a better coordination of guano extraction and conservancy policies.


Behavior of Parent and Nestling Brown Pelicans During Early Brood Rearing
Parent and nestling behavior during early chick rearing were examined at a colony in Charleston Harbor, South Carolina and suggested that any spatial or temporal comparisons of parent or chick behavior should be assessed in relation to the age category of the parent and the age of the chicks.
Widespread Cannibalism by Fledglings in a Nesting Colony of Black‐crowned Night-Herons
In 1 of 5 years, cannibalism of nestlings that had fallen or climbed out of nests was common, accounting for 66 of 94 prey items taken by fledglings.
Non-breeding Nazca Boobies (Sula Granti) Show Social and Sexual Interest in Chicks: Behavioural and Ecological Aspects
Using a 20 year database from a large Nazca booby colony on Isla Espanola, Galapagos Islands, Ecuador, the behaviour and the individuals performing the behaviour are described and a number of hypotheses are proposed to explain the causation.
Growth and Development of Nestling Brown Pelicans
This study analyzes growth data of four nesting seasons for the Brown Pelican (Pelecanus occidentalis) to determine the age and growth parameters for this species and examine weight, and other characters such as bill, wing, and tarsus lengths as a measure of growth in this species.

Estimates of inclusive fitness of chicks in experimental broods were higher than were those of control nestlings, a result inconsistent with the POC hypothesis that the siblicidal offspring's optimal brood size is one while the parents' optimum is greater than one.
Effects of habitat modification on breeding seabirds: A case study in Central Chile
The Humboldt Penguin colony at Paijaro Niflo Island, central Chile, has undergone major modifications, including its joining to the mainland by a causeway and the removal of its pine forest, and the modifications provided new nesting habitats in which reproductive success has been similar to that observed in natural habitats.
Cannibalism in the Australian Pelican (Pelecanus conspicillatus)and Australian White Ibis (Threskiornis molucca)
First evidence of cannibalism in fledglings of the Australian White Ibis and Australian Pelican and pelican nestlings is provided.
Breeding distribution and abundance of seabirds on islands off north-central Chile
Despite protective status, most of the islands showed human disturbance, derived mainly from guano harvesting, egging and tourism, and introduced mammals including rats, rabbits and cats are likely to be detrimental to seabirds and thus demand detailed assessment.
Evolution of Obligate Siblicide in Boobies. 1. A Test of the Insurance-Egg Hypothesis
A field study of the obligately siblicidal masked booby demonstrated that second eggs contribute a surviving hatchling after the first egg's failure in 19.2% of two-egg clutches.
Social Stimuli, Testosterone, and Aggression in Gull Chicks: Support for the Challenge Hypothesis
It is concluded that the initial exposure to elevated T-levels increases the sensitivity to brief changes in T induced by social challenges, and exposure to T, that may be detrimental for development, is minimized while birds remain able to defend territories.
