Tool-use in Charadrii: Active Bait-Fishing by a Herring Gull

  author={Pierre-Yves Henry and J.-C. Aznar},
Abstract An adult Herring Gull (Larus argentatus) was observed baiting Goldfish (Carassius auratus) with pieces of bread. Active bait-fishing is mostly known from herons, and a similar behavior was reported in captivity for a Lesser Black-backed Gull (L. fuscus). To our knowledge, we report the first record of bait-fishing, and second record of complex tool-use, for the superorder Charadrii under natural conditions. 

Fledgling Double-crested Cormorants Rehearse a Food Manipulation Technique with Woody Debris, Algae, and Shells

Fledgling Double-crested Cormorants were observed practicing food manipulation techniques with large sticks, algae, and shells at their respective natal colonies in eastern Lake Ontario, North Channel of Lake Huron, and Lake of the Woods.

Little Egret (Egretta garzetta) and Grey Heron (Ardea cinerea) Using Bait for Fishing in Kenya

A wild Little Egret was observed to take bread, drop it in a pond, wait for the fish to be attracted to the bread, strike at the fish, and successfully catch fish in this way (active bait-fishing).

Observations of a novel predatory gull behavior on an invasive ascidian: A new consequence of coastal urban sprawl?

An observation of a novel foraging behavior of the European Herring Gull (Larus argentatus) is reported: the capture and consumption of the widespread sea squirt Ciona intestinalis from under floating pontoons in a recreational marina in Ireland.

Pecking response in Lesser Black-backed Gull chicks, Larus fuscus

Investigation of the pecking response of the Lesser Black-backed Gull Larus fuscus found evidence that supernormal pecking is an adaptation to innate feeding preferences, with chicks choosing food items that shared properties with the supernormal stimulus (the white stripes, the red colour and the thinness).

Fishing with a Bait or Lure: A Brief Review of the Cognitive Issues

It is concluded that bait fishing is a real and distinctive behaviour and that bait items are both selected from and placed within the environment to achieve enhanced prey capture success.

Waterbird solves the string-pull test

String-pulling is among the most widespread cognitive tasks used to test problem-solving skills in mammals and birds. The task requires animals to comprehend that pulling on a non-valuable string

A Tool for Every Job: Assessing the Need for a Universal Definition of Tool Use

It is demonstrated that many behaviors recently described as tool use do not meet criteria for prevalent definitions, while other neglected behaviors may constitute a form of tool use.

Artificial Intelligence Approaches to Estimate the Transport Energy Demand in Turkey

The efficient hybridization of the seagull optimization and very optimistic method of minimization metaheuristic algorithms is carried out to achieve the polynomial fitting of the data.



Goliath Heron Fishing with an Artificial Bait?

An observation of a Goliath Heron (Ardea goliath) apparently using a small stick as a lure to attract fish is reported.

Bait-fishing has also been observed in the Green Heron and the closely-related Striated Heron (Butorides striatus); a related foraging technique has been reported in the Great Egret and the Great Blue Heron.

Tool use by bristle-thighed curlews feeding on albatross eggs

Five cases of tool use by Bristlethighed Curlews (Numenius tahitiensis) feeding on albatross eggs are reported and it is suggested that tool use is an extension of the "slamming" behavior commonly employed by foraging Bristle-thighedCurlews.

Tools and brains in birds

It is shown that relative size of the neostriatum and whole brain distinguish the true and borderline categories in birds using tools to obtain food or water and that the complex cognitive processes involved in tool use may have repeatedly co-evolved with large brains in several orders of birds.

Feeding innovations and forebrain size in birds

The study confirms predicted trends linking opportunism, brain size and rate of structural evolution and suggests that innovation rate in the field may be a useful measure of behavioural plasticity.
