Booklover - Melinda gave me this idea for a discussion - thanks.
Blue-Footed Boobies are between 80 and 85 cms (32 - 34 inches) in length, they have a wingspan of approximately 158 cms (62 inches) and they weigh approximately 1.5 kgs (3.25 lbs). Males are smaller and lighter than females.
They are adapted for diving, having a cigar shaped body, narrow wings, a long, pointed tail and permanently closed nostrils. Their wings are brown in colour and their underside is pale.
They get their name from their vivid blue legs and feet with males and younger birds having lighter feet than females.Blue-Footed Boobies have yellow coloured eyes that are placed on either side of their bill and oriented towards the front of the head. They have excellent vision which they use to locate their prey.Males communicate using high-pitched whistles and females make a lower honking sound.
Blue-Footed Boobies are found from western Mexico to north west South America and on the Galapagos Islands. They are marine birds that only come to shore to breed.
The largest breeding population is found on the Galapagos Islands and it consists of approximately half of all breeding pairs.

This is an excellent article. Thanks Melinda and Steph. I would surely like to know how their beautiful blue feet evolved.
