Many, perhaps most, people who witness large roosts or the flight lines to them are reminded of Alfred Hitchcock’s movie “The Birds.”
Although it is one of the most natural things in the world, I would like to know if how would you react if you had so many crows flying over your head:
This frightening video of a giant roost of crows was captured over the city of Tursunzade, Tajikistan end of October 2017.
As explained by Cornell University: ‘Crows have been congregating in large roosts in the fall and winter for as long as there have been crows. Crow roosts can range from small scattered roosts of under one hundred individuals to the spectacularly large roosts of hundreds of thousands, or even more than a million crows! A roost in Fort Cobb, Oklahoma was estimated to hold over two million crows (Gerald Iams, 1972, State of Oklahoma Upland Game Inventory W-82-R-10). Most roosts are much smaller, but roosts of tens of thousands are common.’
What are roost?
One of the great animal phenomena of the world is the congregation of large numbers of birds into a single group to sleep together. Such communal sleeping groups are known as “roosts.” Before heading to roost, crows will congregate in some area away from the final roosting site, usually an hour or two before complete darkness. Right at dark the main body of the group will move toward the final roosting spot. Sometimes this final movement is relatively quiet, but usually it is still quite noisy.
So next time you see such a huge flock of crows, don’t be afraid and just enjoy the amazing phenomenon!
