Yeah. That's what I said. That both countries have a mix of migrating and nonmigrating species of birds.
But the US has at least two birds that were recently introduced from England. And both are now considered to be pests. One is the English sparrow, and the other is the starling.
A small club of people released about 100 starlings into Central Park in New York City in the 1890s.
There were no starlings here before that.
The birds thrived, and then multiplied, and then spread beyond the Big Apple, and today...there are millions of them everywhere in the US east of the Rockies.
The reason that those folks released the original starlings in Central Park?
They were a club of folks who had as a mission to introduce into America every bird that is mentioned in the works of William Shakespeare!
Seems a bit "bird brained" to me. But I suppose that folks have found even dumber reasons to do things.

You mention starlings. What a fascinating bird. They copy sounds.
Where we used to live, the row of houses opposite were one by one having new roofs fitted. They no longer wanted old fasion slate and wanted to modernize them and fit concrete style tyles. Our house was old and had been modernized about 80 to 200 years before and the old thatch had been removed and lovely light blue Pembrokeshire tiles. The houses opposite had the duller purple North Wales slates which could have lasted many years more but they wanted modern so were changing.
Now naturally the roofing people were hammering on the rooves. Taking the old slates and chucking them in skips (There was not the market for keeping the slates intact in those days.. 20+ years later slates have become expensive)... Then hammering on the new tiles. Some of the roofs sagged under the weight as the slates were lighter then the new tiles but they were not to know, and the roofers didn't know because they had no long changed to the tiles, and were all out busy when the fasion to change had caught.... Knock knock knock... We lives on a bank higher then the houses opposite so we were looking down on them in a way. The sound of knocking was amplified due to the way the accoustics hit us. The traffic on the road used to rattle our windows! So the sound of knocking went on and on. Uhmm. On and on. The weeks turned into months. Surely the roofers had long finnished changing the rooves? They had. Months later the starlings were repeating the sound with such accuracy!
We had fun when cars started to be fitted with alarma. These birds would copy and whole towns had alarms going off!
The funny one... We would hear a siren of an anbulance, police car, fire engine or the coastguard and we would look at the road to see what was passing.... Nothing. It was those birds again!
WTF?
Your starlings mimic ambient man made noise?
Never heard, nor heard of, starlings doing that here in the States.
Mockingbirds are called that because they imitate the songs of other bird species.
And parrots can be taught to "talk" (ie repeat your human language words).
And myna birds do that one better by not only repeating your words, but actually reproducing the sound of your voice when you say those words (like a living tape recorder).
And there was a memorable moment in a David Attenborough nature doc which showed a large bird in the depths of the New Guinea jungle (the lyre bird maybe?) that reproduced the sounds of things like chainsaws, and a bunch of other manmade machines that intrude into its environment.
But I never heard, nor heard of, of those little short tailed black birds, that are as common as dirt around here in Rockville Maryland doing that sort of thing.
