Hi all,
Can anyone tell me please how birds (passerines) migrate; I mean what is the favorite weather condition in terms of wind direction and speed preferable by passerines? Do they travel with or against the wind direction? Do they experience the same wind direction and speed at the height that they travel through? Because from my observations I noticed that migrating passerines arrive altogether and leave altogether, although they different species.
