The average bird meal consisted of 90.8% honey bees and 9.2% beetles. [28] Predation is more likely when the bees are queening or during the peak of migration, from late March till mid-April, and in mid-September. Hives close to or under trees or overhead cables are at increased risk as the birds pounce on flying insects from these perches. [29]
The behaviour of social insects (insects that live in colonies, such as ants, bees, wasps and termites) has always been a source of fascination for children, naturalists and artists. Individual insects seem to do their own thing without any central control, yet the colony as a whole behaves in a highly coordinated manner. [ 66 ]
The average bird meal consisted of 90.8% honey bees and 9.2% beetles. [11] Predation is more likely when the bees are queening or during peak migrations, from late March till mid-April, and in mid-September. Hives close to or under trees or overhead cables are also at increased risk as the birds pounce on flying insects from these perches. [12]
The Arctic tern has the longest migration journey of any bird: it flies from its Arctic breeding grounds to the Antarctic and back again each year, a distance of at least 19,000 km (12,000 mi), giving it two summers every year. [18] Bird migration is controlled primarily by day length, signalled by hormonal changes in the bird's body. [19]
Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. [5] It is found in all major animal groups, including birds, [6] mammals, [7] fish, [8] [9] reptiles, [10] amphibians, insects, [11] and crustaceans.
In 2018, a study out of UW-Madison that analyzed bat poop found that little brown bats in Wisconsin were eating 17 different types of mosquitoes, including nine that carry West Nile virus.
Animals including mammals, birds and insects such as bees and wasps (Ammophila and Sphex), [12] are capable of learning landmarks in their environment, and of using these in navigation. [ 13 ] Yellowjacket wasps using a stone as a landmark to navigate to their nest entrance.
A high-elevation meadow in the Oregon Coast Range is helping uncommon wildlife like purple martins, bats and bees. Walker Meadows is around 13 miles west of Veneta and at an elevation of 2,300 feet.
