Gannets hunt fish by diving from a height into the sea and pursuing
their prey underwater. Gannets have a number of adaptations which
enable them to do this: they have no external nostrils; they have air
sacs in their face and chest under their skin which act like
bubble-wrap, cushioning the impact with the water; their eyes are
positioned far enough forward on their face to give them binocular
vision, allowing them to judge distances accurately. Gannets can dive
from a height of 30 m, achieving speeds of 100 km/h as they strike the
water, enabling
them to catch fish much deeper than most airborne birds.
Mainly white bodies, with long, black-tipped wings. Their heads are
large, yellowish with black marks around their eyes. They have
straight, sharp, tapered bills and pointed tails.Young Gannets are
completely black achieving a little more white plumage each year until
maturity in 3 to 4 years.
