Great shots!

Very pretty

The actual air-speed velocity of an unladen swallow, African or European, is anywhere from 25-45 mph. He'd have to hit 65 mph just to get into the Top Ten of Worlds fastest birds.

A Peregrine Falcon can dive between 125-170 mph (some say 200 mph) but can't match anywhere near half of that speed on level flight. Also not in the Top Ten.

The fastest bird is the Spine-tailed Swift, they hit straight-line speeds up to 105 mph. To get that one Zig you'd have to pan at 1/1,000 and get real lucky to sync it.

"In order to maintain airspeed velocity, a swallow needs to beat its wings forty-three times every second, right?"
WRONG! It's more in the range of 7-18 beats per second.

And "What is the capital of Assyria?" was a trick question! Poor Sir Robin could have saved his life and the lives of Sir Gawain (his death was cut from the movie) and Sir Galahad by stumping the Bridgkeeper! There were actually four capitals of Assyria:
Ashur or Qalat Sherqat
Calah or Nimrud
Dur Sharrukin or Khorsabad
and Nineveh

As I told Sir Bedevere the Wise, when you're a Grail-head and former Swap-nazi, you have to know these things!

Killer pics as usual by the way! You rock the shutter dude!!!
