Black Headed Gulls chasing and catching Turnstones (1 Viewer)

I was at Preston Sands near Paignton yesterday, there were a lot of Turnstones present and I noticed that often as they took flight out over the sea they were pursued by BH Gulls, in one case I saw a BH gull catch a turnstone and then fly off with it. This was not something that I was shocked or surprised by but it is not something that I have either seen or have heard mentioned before.
 
Possibly an injured bird? I would think a fit Turnstone could easily outrun a BHG! I did watch BHG's going after a Little Auk a few years back but the LA was so tiny in comparison, so it was probably a case of opportunistic behaviour (bullying b*stards I thought at the time!)

I don't think it was an injured bird, I just think the the BH Gull got lucky, the fact that the BH Gulls seemed all be trying it suggests to me that they had done it in the past and that the effort was worthwhile to them.

Sounds unusual to me - GBBGulls would've been more likely.

Did you really see a Black-headed Gull catch a Turnstone in flight and fly off with it?

That is what I have just said, and that is what I saw. There were several BH Gulls at it and usually two or three chasing single turnstones, so the turnstones that were being chased were having to try to evade more than one BH Gull at once.

A turnstone isn't all that much bigger than a Little Auk, and it was certainly opportunistic behaviour.

Yes, sorry if that sounded as doubting as it reads!

Still a bit surprised that you weren't surprised though, if you know what I mean*. Maybe someone with a BWP can look up BH Gull and prey items - a quick google search doesn't really indicate them being that predatory beyond invertebrates etc.



*(Obviously you must have been a bit surprised? Otherwise you wouldn't have posted the sighting on here?)

Edit: and I once saw a Moorhen kill a turnstone!

Seen BH gulls chasing smaller waders numerous times but usually they are only after what food these waders have found.
 
It just didn't surprise me that a BH Gull would kill something if it had the chance and it was potential food, I suppose the BH Gull catching the turnstone was simply a further extension of trying to take food from it. Its just that I have not so far found any mention of other birds as prey items for BH Gulls.

The crows killing a BH Gull if they got the chance would not surprise me. It may be that originally it started out as a tussle over food between a BH Gull and a Crow and the Crow got the upperhand and realised that the Gull was a potential food item, and has done it again.
 
Black-headed Gulls do take chicks of other birds but never heard them kill an adult before. I have seen Jackdaws chase smaller waders maybe trying to tire them out?

Crows hav been recorded killing birds upto Lapwing and BH gull size previously.

Moorhen killing a Turnstone? No wonder Coots hate Moorhens!
 
Water Rails have been observed catching and eating small passerines such as Greenfinches in harsh winters.

And Turnstones feeding on dead human corpses.

Full circle and anything goes I guess.
 
Once saw BH Gulls having a good go at trying to catch a storm blown Leachs Storm Petrel but presume it was a somewhat weakened bird.....but it did get away intact
 
It is not uncommon here for several BHG to pick on a healthy Lapwing till it is exhausted and kill it. As on a previous post I have seen Crows pick on a healthy BHG and kill it.

Really? A Greenfinch is not much smaller than a Water Rail! Shocking!

I always thought that BHG's got on with Lapwings and the only serious Gull predator they had were GBBG's. I have never even heard of Herring or Lesser Blacks killing Lapwings.

I have never seen Crows pick on BHG's but it appears to happen quite a bit judging by others experiences. Crows seem to be more predatory than Ravens at times.

I assume Med Gulls and Common Gulls will be even more predatory due to their larger size than BHG's? On the other hand i have never read or heard about Common Gulls robbing eggs and chicks of other birds.

I don't think size matters all that much, the Great Grey Shrike is only about the size of blackbird but has been recorded as taking birds as large a Fieldfares. BH Gulls are actually quite agile in flight, my perception is that they are more agile than the larger gulls and if you get two or three of them picking on a single bird as I saw it should not come as any surprise that they might pick on other species of bird. They are opportunist feeders after all.

As to crows I have seen them trying to kill rabbits and on one occasion I have seen a a pair of carrion crows having a go at a very small dog and in that case I think that the dog was being seen as a potential food item (it was certainly a very frightened dog when I rescued it).
 
Moorhen killing a Turnstone? No wonder Coots hate Moorhens!

It was many years ago at Elmley RSPB in Kent. It was in Spring and an adult Turnstone wandered too close to a family party of Moorhen. The young had only recently hatched and the female Moorhen (presumably) felt that the Turnstone was a threat and immediately jumped onto the back of the Turnstone and pecked at the back of its head. As with the B H Gull, the initially blows to the head must have left it too dazed to simply fly off. The attack continued until the Turnstone was out cold. Then, and this is macabre, the Moorhen pushed the Turnstone a few inches so that its head was under water. It then held it there until the bird was certainly dead.

Cheers, Andy.
 
I have watched Coots fighting Coots and Moorhens fighting Moorhens, although the fights look similar the Moorhen fights do seem to go on longer and seem more vicious.
