Starlings on Otmor

Starling Magic

(Updated Aug 3) After posting these videos last night, I decided to see if this habit might be mentioned in Scripture and here is what I found:

Like birds flying about, So will the LORD of hosts defend Jerusalem. Defending, He will also deliver it; Passing over, He will preserve it.” (Isaiah 31:5 NKJV)
Then I saw an angel standing in the sun; and he cried with a loud voice, saying to all the birds that fly in the midst of heaven, “Come and gather together for the supper of the great God, (Revelation 19:17 NKJV)
Who are these who fly like a cloud, And like doves to their roosts? (Isaiah 60:8 NKJV)

Here is an interesting commentary quote from Matthew Henry:
“(4.) These converts flocking to the church shall be greatly admired (Isa_60:8): Who are these that fly as a cloud? Observe,
[1.] How the conversion of souls is here described. It is flying to Christ and to his church, for thither we are directed; it is flying like a cloud, though in great multitudes, so as to overspread the heavens, yet with great unanimity, all as one cloud. They shall come with speed, as a cloud flying on the wings of the wind, and come openly, and in the view of all, their very enemies beholding them (Rev_11:12), and yet not able to hinder them. They shall fly as doves to their windows, in great flights, many together; they fly on the wings of the harmless dove, which flies low, denoting their innocency and humility. They fly to Christ, to the church, to the word and ordinances, as doves, by instinct, to their own windows, to their own home; thither they fly for refuge and shelter when they are pursued by the birds of prey, and thither they fly for rest when they have been wandering and are weary, as Noah’s dove to the ark.
[2.] How the conversion of souls is here admired. It is spoken of with wonder and pleasure: Who are these? We have reason to wonder that so many flock to Christ: when we see them all together we shall wonder whence they all came. And we have reason to admire with pleasure and affection those that do flock to him: Who are these? How excellent, how amiable are they! What a pleasant sight is it to see poor souls hastening to Christ, with a full resolution to abide with him!”
