Hi
We have a large weeping willow in the garden and this year a goosander has started nesting in a hole in the tree.
When checking the nest today, I disturbed a tawny owl and it appears that they are in competition for the nest hole.
As you can see from the photo below, the nest now contains 3 goosander eggs and 1 tawny owl egg (the smaller round egg to the right)
Any advice as to how this might play out? Are both likely to abandon? Thoughts and comments welcomed
