Huiszwaluwen (House martins) 

It's fascinating to watch the birds flying back and forth their nests.

Great builders! A joy to watch!

This is so beautiful ❤

Excellent video. great channel.May you have a nice day.

Leuk dat je ook het bouwen van het nest hebt kunnen filmen

I have never known that they nest in the house, that's why people call them House martins. Great. They are not common in our area. Thank yo use much for sharing, dear.
