Nope, shags are different

 

 

Not according to Christopher Isherwood

 

The Common Cormorant or shag
Lays eggs inside a paper bag.
The reason you will see no doubt
It is to keep the lightning out.
But what these unobservant birds
Have never noticed is that herds
Of wandering bears may come with buns
And steal the bags to hold the crumbs.

I hope you don't get them in large numbers!  I live on a large river and thousands of cormorants have moved in. I don't know about fish damage but they roost in large numbers. Poo in large volumes and the ammonia is so strong you don't want to get near the Island.  It also decimates all the plant life under them. Once the trees die they move to a new spot and start all over again.

 

We have an are locally called 'The Islands', as the name implies it is a string of several islands, from small to a 3 or 4 acres. They have roosted there starting on the smaller islands. Decimated those, erosion without the greenery started and a couple of small islands were lost.  The larger islands suffered badly but they moved to the other ends and started it all over.

They always look very low in the water. Failed automatic bilge pump no doubt.

That's because their buoyancy has to be delicately balanced in order for them to dive efficiently and fresh water is less dense than salt, so they always look like they are struggling a bit. Sorry to be both late and pedantic, but it’s one factoid I always remember about them!

Excellent bit of trivia

I was quite surprised to see a cormorant on the Tring summit this week.
