Large prey items of birds of prey

As it's approaching Christmas holidays for some, I thought I'd invite members to mull over this (with their mulled wine perhaps!), prompted by the following observation I found in the Recent Sightings section of www.western-isles-wildlife.com

"15th December:
North Uist: A Glossy Ibis was seen at Loch na Revil early this afternoon shortly before being killed by a Buzzard."

Pretty big prey item I thought, so......

What's the biggest bird/animal/fish you've seen killed by a bird of prey?

Golden Eagles have been known to chase Red Deer off cliffs, and its difficult to imagine any greater mismatch than that unless someone has a colony of Rocs near them.

Saw a Peregrine knock a Mallard out of the sky once. Unfortunately because of my presence, the Peregrine flew around and then away (I was out running at the time). The Mallard just staggered around a bit wondering what the ????

Not natural of course, but this is pretty insane.

I'd also heard of this claim John, but wondered if it was really documented or one of those apocryphal tales, here in the French Alps one of the 'justifications' for the original extermination of Lammergeier was that they also forced sheep etc off cliffs......

Golden Eagles have been reported taking every dirunal BoP. I have also seen footage of them taking Red Fox and pulling Mountain Goats of cliff edges.

No, its not apocryphal. John Aitchison filmed the behaviour (though did not record an actual kill) for the BBC, up the Findhorn valley. I saw it: there is no possibility of misinterpretation.

Thanks for that John, I suppose that once the deer fell off the cliff it was technically a kill anyway!!!

Yes, but the eagle had chosen a bad place for its attempt: the deer survived intact. However it was obvious that a serious, deliberate attempt to harass the deer into a mistake had been made: it wasn't an accidental startling of it.

Not enough - populations still rising. Anyway, even in these days of obesity most children are still smaller than Red Deer!

Spanish Imperial Eagles take Red Fox. I've never seen them actually make a kill. Though, on one memorable day, we watched a fox chasing an Iberian Hare when 2 SI Eagles hunting co-operatively interrupted the chase at low level - the hare went one way and the fox another (to hell with the hare!) - the eagles went after both, one for each. They didn't manage to catch anything but it was an incredible sight!

Weight wise though glossy ibis isn't that heavy/bulky, probably similar in weight or lighter than most ducks or a large rabbit. Plus if you've seen the weather the glossy ibis have had to put up with here of late it probably wouldn't be in the best of health!! The ones I saw on Monday were flying backwards in the wind.

cheers, Andrew

Er, does that include WTE, Bald Eagle, Steller's Sea Eagle, Imperial Eagle, or any kind of vulture the size of a Griffon Vulture? I mean I've read about Eagle Owls being killed in the occasional nesting site dispute with larger eagles, but never about the large eagles predating each other.

I've seen Goshawk taking 1cy Herring Gull mid air - a prey that's basically the same size as Goshawk itself. And heard about White-tailed Eagle attacking Greylag Goose.

On that note, I've seen a WTE kill a (Greater) White-fronted Goose.

I haven't seen a bird of prey take anything very large. The usual Red-tails with gophers and Peregrines with pigeons. I do have a Great Egret who frequents my yard that eats gophers. He has to move them around quite a bit before he can swallow them.

I once flushed a Bald Eagle off a recently dead Canada Goose, though I didn't actually witness the kill.

Sangahyando.
My apologies, Golden Eagles have been observed and recorded in the Scottish Highland taking most British BoP no doubt this does not include WTE, but when the book I am referring to was wrote WTE were still quite rare, this behaviour was observed by the author/naturalist Mike Tomkies.

Right on! Do you remember the tv documentary which advised that Eagle Owls snatched babies from their prams when their main food source, the pet moggie, was scarce? Must be true!

On a more sensible note, surely Haast's Eagle taking Moa (probably not Giant) must be a candidate?

Not a bird of prey but the most insane predator-prey battle I have ever seen was a Cormorant trying to catch a full-grown Pike:

I noticed a commotion in the water; looked and saw a cormorant surfaced with a truly massive Pike partly gripped in its bill - the Cormorant had only managed to grip the Pike's head and was struggling trying to pull the rest of it out of the water (it never managed to pull out more than half the fish). I have no idea what it intended to do next as the Pike was much wider than the Comorant's neck and must have weighed a fair fraction of the Comorant's weight.

The result was a lot of splashing and thrashing, the Comorant being pulled under twice and finally (sensibly) letting go of the Pike and swimming away.

Of course! And let's not forget those pesky Red Kites that also try this. Seems a good idea really - population control at its most natural!

Then there was the famous film by the late Felix Rodrigues de la Fuente of a golden eagle knocking off a cliff a full size mountain goat and then following it down until it hit the ground below,It then fed on the animal,spectacular filming in the 1970's.,,Eddy
