In Primorsky Krai in Russia, 53.2% of the food for the eagle-owls were made up of birds, predominantly water birds with the primary prey species being the 260 g (9.2 oz) crested auklet (Aethia cristatella) (26.9%). [106] [114] In the Russian Far East, similarly, birds occupy up to 57.6% of the diet, a lion's share of which are water birds.
In the stated study, the tawny owls would kill and eat amphibians and fish, while the long-eared owls would rarely kill and never eat these types of prey. [36] In a study of five European biomes , with about 45 prey species per biome, the tawny owl was estimated to have tied for the second most prey species per biome after the Eurasian eagle ...
Arizona has 13 species of owl, including great horned owls, barn owls and screech owls. Here's where they live and what to do if you encounter one.
However, because they need to eat less food in order to survive, least chipmunks are more numerous where resources are scarce. [10] They are agile animals, and have been recorded running at speeds of up to 7.7 km/h (4.8 mph) in natural conditions. [11] Predators include hawks, owls, and mustelids. [citation needed]
Tawny and brown fish owls are both slightly smaller than co-occurring Eurasian eagle-owls, and Blakiston's fish owls are similar or slightly larger than co-occurring large northern eagle-owls. Fish owls, being tied to the edges of fresh water, where they hunt mainly fish and crabs, also have slightly differing, and more narrow, habitat preferences.
Allen's chipmunk has been observed to live as long as 8 years in the wild. However, due to a lack of data on Allen's chipmunk, specifics on its life expectancy are unknown. [11] Natural predators of Allen's chipmunk include hawks, owls, foxes, coyotes, snakes, badgers, and weasels. [12]
The eggs are typically laid directly on the rotten wooden floor of the nesting cavity; owls do not build a nest. Egg-laying intervals are up to 4 days between the first and second egg, an unusually long interval for an owl. The female appears to do all incubation and the incubating stage is 36 to 38 days. [29]
