White Tern Gygis alba
One of the most beautiful and interesting of birds, the
White Tern is a year round resident and breeder. We saw them every day,
everywhere. Typical of tropical birds they breed all year long. |

The White Tern is an all white bird with blue feet and legs
and a black bill, blue at the base. This bird has been called Fairy Tern
although that name is now reserved for an Australian tern which looks more like
the Least Tern. This bird casually lays its egg in any convenient nook on the
bare branches of tree. Both the female above and the one to the left seem to
have found a a place in the fork between branches. As demonstrated by these
pictures a second bird frequently hung around the incubating bird. I often
observed 3 adult plumage birds flying together, suggesting that perhaps they
represent a pair and an adult offspring. |

Any little hole seems to suit the White Tern for its egg.
Here an egg rests in hole in a porch railing. The parent bird was flitting
around the porch when our group trooped into the small museum in the house
occupied by the refuge manager. This residence was formerly that of the highest
ranking officer on the base. This picture was taken during the rain on the
first day of our visit. |

I cannot see an egg in this picture, but this adult bird
seems to be very relaxed. I was some 15 feet away on the path when the picture
was taken with a telephoto lens.
White Terns share the Ironwood trees
introduced by the cable company with the Canaries. According to the ranger, the
White Tern will also nest in the lower native vegetation. |
|
An egg laid in an exposed and precarious place results in a
chick that must cling to the perch for dear life. This little guy hatched on
the top of a wood rack used for drying nets. He was still healthy several days
later. After two days of heavy rains we did find a dead chick at the base on
one of the Ironwood trees like those is the pictures at the top of the page.

Notice the pair of white terns perched on the
sign close to a busy pedestrian sidewalk. Are they checking this out for a
nest? This Midway Mall consists of store with film, a few groceries, cosmetics,
souveniers and other convenience store items, but without convenience store
hours. They were mostly closed. Fortunately for us they had a line of umbrellas
which we purchased when it rained most of our first two days on the island. In
the back ground the bowling alley a standard feature of any US military base.
This one is used primarily by the workers on the island. |
Sooty Tern Sterna fuscata
Sooty Terns also breed on the island. We had our best looks
at this handsome bird on the weekly walk on Eastern Island. |
