Avian foraging

144:. Various attempts have been made to classify foraging guilds for ecological studies and universal and undisputed classifications do not exist. It must also be noted that species may belong to multiple foraging guilds depending on situation (for example, while breeding, in migration, or in disturbed habitats). Specific classifications are used in ecological and behavioural studies. The classifications are often made according to multiple hierarchical criteria and a full classification may include multiple terms. To take an example a bird may be described as "nocturnal gleaning insectivore" with parts of the classification dealing with the time of day, the diet and the technique used to obtain food. 493:). The behaviour is exhibited while perched in shallow water, and sometimes on dry land, over short grass or bare soil. The gulls rapidly move their feet up and down while staying at a spot and it is thought that this flushes subterranean prey that they then detect and feed on although there is no definite evidence. Other terms describing the term have included paddling, puddling, pumping, stamping, thumping, tramping, trampling, treading and trembling. The behaviour is found in young gulls and is considered to be innate and does not require learning. The behaviour has been compared by lay observers to rapid dancing moves. 36:. Foraging includes a range of activities, starting with the search for food, making use of sensory abilities, and which may involve one or more birds either of a single or even of multiple species. This is followed by locomotion and movements to obtain or capture the food, followed by the processing or handling of the foods prior to ingestion. Like all organisms foraging entails balancing the energy spent (in search, locomotion, avoiding predators, handling food) and energy gained. The high metabolic rate of birds, among the highest in the 17: 2727: 2751: 63: 2763: 2739: 438:, fly-catching, or aerial sallying refers to obtaining aerial food, typically flying insects. The birds typically stay on the wing while handling and ingesting the prey. The more specific term flycatching is used to describe birds that fly out of a perch to capture and insect to return with the prey to a perch before handling the prey. 311: 478:
movements may be used by waders such as plovers and lapwings. They are used mainly on wet soil or while wading in shallow water. Some waders move around rapidly in circles, these include the phalaropes, best known for their pirouetting movements, often in deeper water that reaches until their body.

Foraging involves expending energy and seeking food can be both time and energy consuming. Birds make use of a variety of approaches to improve the efficiency of their foraging. These include foraging in flocks which provides many eyes to seek patches rich in food while also reducing the risk of

It is found mainly when hosts are found in numbers and when the food item is large and visible. 460: 314: 319: 317: 313: 312: 318: 334:
