For example, birds use different memory systems and different rules for remembering species song, the taste of poisonous food, and locations of food caches.
The model was fitted separately to decisions made by blue tits and great tits, and we fitted separate s parameters for conspecifics and heterospecifics in order to determine whether birds used different rules for different components of their flocks.
In this figure, we illustrate the result obtained for the image 'Barbara' compared with SR algorithm using TV regularization and the RSR Fig. 4 a d Results obtained for image 'Bird' using different methods.
Of the five birds with valid manufacture sequences for both matched and control stems, three used the same first action (place of grip and place of detachment) for both stems, one attempted to do so (incomplete action for control stem), and one bird used different first action types.
Parametric analyses have been performed using different bird sizes, impact locations and velocity vectors.
It's not exactly clear why some different birds use these different strategies.
Scientists have known for 30 years that small birds often use different calls to relay information about predators.
A redistribution of AIV among birds that use different migration routes may well contribute to the survival of the virus across a wide geographic range.
--Turkeys have both white and dark meat, which is actually two different types of muscle tissue that the birds use for different purposes.
