Some time ago I noticed two pairs of great blue herons building nests at the same tree. Once one pair left their half-built nest unguarded. A heron from another nest decided it was a great opportunity to improve his/her own nest. For the next 40 minutes or so the heron made many trips between the nests, stealing sticks. I filmed only part of this activities.

This theft worked for the best of the thief. They now have three cute chicks, while the herons from another nest are still incubating because they had to rebuild the nest from scratch.
I observed a similar behavior in Antarctic, where some kind of penguins stealing stones from their neighbors nests.
