The birds know something we don't

This year I've noticed a larger than usual number of vultures in this area than usual.
They're here year round but this is hte most I've seen in the surrounding area in 10 years.
They fly high and low and circle looking for road kill which is dosn't seem to be as plentiful for them this year.
They spend more time on the trees getting hungry.

It's like they're waiting for something to happen ?

I'm sure the Lord will feed them as He does all His creation.

And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God;
That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great.
And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army.
And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.

And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh.
