Title: How high do Birds fly during migration? Post by: Donna on 27-Sep-11, 06:37:41 AM Birds usually fly relatively low. Most of the year, they stay under 500 feet. During migration, though, birds gain altitude, and many species fly at 2,000 to 5,000 feet or higher, using prevailing winds to assist them. A bird may begin migration at about 5,000 feet and slowly climb to 20,000 feet. Birds can fly higher as they become lighter. The record flight is for a Rüppell’s Griffon — like this one — which was unfortunately sucked into a jet engine at 37,900 feet.

Title: Re: How high do Birds fly during migration? Post by: Donna on 27-Sep-11, 06:58:49 AM :wow: How do they stand the cold temperatures up that high!? :natale3: Birds have many physical and behavioral adaptations to keep warm, no matter what the low temperatures of their surroundings. Birds’ feathers provide remarkable insulation against the cold, and many bird species grow extra feathers as part of a late fall molt to give them thicker protection in the winter. The oil that coats birds’ feathers also provides insulation as well as waterproofing. So, there ya go!! (Google told me) :clap: Title: Re: How high do Birds fly during migration?
