I confess I haven't read it all yet. http://www.biology.eku.edu/RITCHISO/birdbrain2.html #115603 - 11/10/03 09:00 PM Re: bird vision   Joined: Dec 2000 Posts: 13,803 Faldage Carpal Tunnel Faldage   Carpal Tunnel Joined: Dec 2000 Posts: 13,803 Just a brief glance looks fascinating. Thanks, Dr Bill. #115604 - 11/10/03 11:48 PM Re: bird vision   Joined: Sep 2001 Posts: 6,296 Wordwind Carpal Tunnel Wordwind   Carpal Tunnel Joined: Sep 2001 Posts: 6,296 Piedmont Region of Virginia, U... I'd just like to understand how those fast fliers navigate through the woods so quickly without apparently hitting themselves in the head with so many branches. I sure as heck have problems sometimes woods navigating at a lethargic pace. #115605 - 11/11/03 12:18 AM Re: bird vision   Joined: Jun 2002 Posts: 7,210 Buffalo Shrdlu Carpal Tunnel Buffalo Shrdlu   Carpal Tunnel Joined: Jun 2002 Posts: 7,210 Vermont another great site, Bill! thanks! formerly known as etaoin... #115606 - 11/11/03 01:59 AM Re: bird vision   Joined: Jan 2001 Posts: 13,858 wwh Carpal Tunnel wwh   Carpal Tunnel Joined: Jan 2001 Posts: 13,858 Dear WW:One of the birds' secrets is the fact that their nerve pathways are relatively short. It takes an appreciable fraction of a second for nerve impulse to travel from brain to an extremity, so small animals can react much sooner than humans can. I think the big dynasaurs must have had to wait a week for message from brain to reach their hind legs. Remember the old parlor trick of telling a kid he can have a dollar hung vertically between his thumb and index finger, if he can close them before dollar drops through them? Kids look very much amazed. #115607 - 11/11/03 10:40 PM Re: bird vision   Joined: Sep 2001 Posts: 6,296 Wordwind Carpal Tunnel Wordwind   Carpal Tunnel Joined: Sep 2001 Posts: 6,296 Piedmont Region of Virginia, U... Oh, many thanks, wwh, for that explanation. I have often wondered how in the world birds navigated so quickly through dense woods. The short nerve pathway does make some sense as a theory, so thanks for giving me that fodder to ponder!
