Interesting. You hear a lot about birds of prey and how good their sight is, but I wonder has anyone ever tested a gull's sight?
They are kind of overlooked. And the larger species are far more predatory than most people think.

Gulls, like most marine birds. have exceptional eyesight and can find food from quite a distance or height. However it's not nearly as developed as the vision of many raptors, who have many more receptors per sq mm and foveas with far more rods and cones that provide extraordinary distance vision.

Compared to humans how much better are raptors.

A lot.


I'm not in to trying to put a comparative measure on all the aspects or factors involved in sight. There's no single measure. But if you have 20/20 vision, they would have 20/4 at least.


To quote from elsewhere

If you had an eagle's eyes you could see an ant crawling on the ground from the roof of a 10-story building. You could make out the expressions on soccer players' faces from the worst seats in the arena. Objects directly in your line of sight would appear magnified, and everything would be brilliantly coloured, rendered in an inconceivable array of shades.

What you describe is an illegal pole trap - I would be reporting such activity to the NPWS or Gardai. Crows can only caged trapped

http://wildlifecrime.ie/pages/Traps.html#GO-Illegal

A number of prosecutions have been brought in recent years in this area

"Pole traps are ILLEGAL

The term "pole trap" refers to a spring trap fastened to the top of a pole and used to kill birds of prey. In the past small circular gin traps were sold for that purpose. Of course gin traps are now illegal but legal traps like fenn traps are sometimes illegally used for this purpose. Birds of prey are very attracted to perching on solitary poles - even with a pole trap on top.

Any person who affixes, places or sets a trap, calculated or likely to cause death or bodily injury to any wild bird coming in contact with it, on any tree, pole, cairn or other structure shall be guilty of an offence"

FFS idiots those who put them there, could have used a cage for the rats

Unfortunately a lot of them end up with the same fate. Driving the m1 the other day saw 2 separate buzzards dead close to roadkill

Very true i fly a trained harris hawk for falconry , and one thing ive learned dont under estimate any Birds eyesight, its not just the birds of prey, its the tiny robin in the garden has amazing eyesight to the super intelligent corvids and gulls there eyesight must be just as good as ive seen them spot me & my harris from over a km away at times, amazing animals ,Birds

Great response, birds of prey also see at a much better frame rate than humans , they almost have a supernatural response to detection of movement!!
I Hunt with a trained Harris Hawk , he is often 3 feet away from my glove before I even know his prey is there!!

I have seen my harris hawk return from 4/500meters away instantly to my falconry glove , at the sight of a piece of meat the size of a piece of popcorn!! No problem at all for them
