its a big bad world out there

...and the harassed drake eventually flew off!
I do wonder if the many non reproductive pairs and trios that are now found away from water around the verges of the avenues and even on campus, where there is no pond, are actually seeking some peace and quiet from all this pond sexual excitement.

The pair watching intently. Their tails are touching and slightly fanned and their belly feathers are also a bit ruffled.
The start of a caw.
The end of a caw.
The intruded came closer and both birds called noisily and gave it chase.
Carrion Crows pair for life, which is often not that long (average 4 years, with a maximum recorded age of 9) and the pair remains together all year round. Only territory holders breed, with one year old birds and non-territory holders often moving in a flock and intruding in territories in search of food, leading to squirmishes with the territory holders, in which both members of the pair participate.

And catching what it looks like a ground beetle larvae.
for the first time, I have only seen one adult with them. The adult apparently decided to build another nest by the island, as the chicks couldn't return to the tree nest. It left the chicks on their own for periods of frantic nest building. The nest is now pretty much done and attracting much attention from the new pair of coots in the park (previous post). I've never seen the chicks on the nest. The number of chicks went from three to two on the 1st of May, but the two left are growing.
One of the chicks had a good look at me.
The young rush to meet their parent for some food.
