There have been several studies that claim to prove this hypothesis while others say just the opposite. [6], It has been found that passerine birds molt in the summer months. This hypothesis has been suggested as anting has no obvious function, it is non-adaptive, birds are said to achieve pleasure from anting and anting has characteristics of a habit. A new one for me too, but I did see a crow doing it a few weeks back (I was driving and on a red traffic light though!). Nests are built in places, which are inaccessible and are concealed from view.

This hypothesis suggests that birds use the chemical secretions that come from ants to control and rid of parasites in their feathers. Those ants live in the sandy substrate under concrete and bricks, where their colonies can range in size from a few individuals to several thousand. Birds use one ant at a time and only rub a feather once with an ant. However, there are some cases where an ant is used more than once but never exceeds three uses.

Even where 20 or more blackbirds feed in close proximity, e.g. In fact, it is thought that urban Blackbird populations may even act as a source for less productive woodland populations, which face significantly greater levels of nest predation.
