Heavy engineering

I am amazed at some of the nests that the crows build during their nesting season. I found two near our colony who have built them on power line posts. One of them on a high tension one as this. I wonder how the crow placed its first sticks to lay the foundation and that too with just a beak and two legs. Incredible!



And here's another one I found located on another electric post. Inside this one the mother was sitting on her eggs.



Now here's some trivia. I also believe the nests are a natural turn on for the Asiatic Koels and as evolution or survival of the species would have it they court, mate and the females go depositing their eggs in these crow nests. How perfect nature is.
