Birds having fun !!!! watch Swallows in summers evenings, darting round and round at full speed in groups of 6 or so, just above the rooftops while you sit in the garden, shrill screaming between each other, like they're having the time of their lives. I can sit for hours watching them, fabulous.
Brilliant thread BTW

.
Some other mentions here...
We had (i havnt seen them for some years now) a small population of Green Parakeets in Longueville school woods in Peterborough, escapees i would think that built a small population...thats sadly gone now i assume. Working in Uruguay, there were loads of them (or similar) in the treetops in the town i was staying....very noisy birds.
Green woodpecker are common here, plenty in the same woods, you can see them particually early mornning in spring and summer mornings in the local urban estate, they've become reasonably accustomed to traffic etc.
Marsh harrier, a really quite rare bird to see, again, there's a reasonable population about 10 miles away on the edge of the nene washes, much bigger than Red Kite (and they're not small). Saw one on a ride this last summer.
I was incredibly lucky to see an Osprey on one ride. Normally you'd only see them as a speck at altitude, but something caught my eye in a copse about 100 yards away...an Osprey sat in treetops. Unmistakeable 'booted' legs and light colouring. Its not unusual to see them in the summer, they nest at
Rutland Water and are seen travelling east toward (i assume) the nene washes...but always very high up.
Then sometimes, i'll use the hybrid to go birdwatching to the local country park (Ferry meadows) where there's a couple of hides. Sat there one day...somehing flitted in the corner by the door...
He (she)'d made the nest just in the gap between the walls and roof...about 4 ft from where i was sitting
Told some of these before..riding one day, something caught my eye in the verge as i passed...an eye

(thats all i saw) WTF was that ??? turned round, and there was a young Jay huddled there, with only one eye !!! (funnily enough, it was yards from where i saw the Osprey). Wished i'd had the camera (as is often the case)
Oooh, i could go on and on.
