{"fact":"Crows sometimes take the scenic route! When flying to their communal roosts, crows will often visit a pre-roost gathering first, almost doubling the distance they travel.","context":"In the cases when the territorial crows roosted communally after attending a pre-roost, they did not differ significantly from the non-territorial crows with respect to distance between daytime location, pre-roost and roost...In these cases, the ratio between the total recorded travel distance from daytime location to roost via pre-roost and the direct distance from daytime location to roost varied from 1.0 (i.e. the pre-roost was located on the straight line from daytime location to roost) to 24, with an average of 1.83±0.21 (n=114).","source":"Geir A.
