Line Island Warbler - Conopoderas aequinoctialis - this species is rare 
on Christmas and common on Washington, but is far less 
conspicuous than in June. 
MAMMALS 
No mammals exist on three (Howland, McKean, and Enderbury) of the 
islands yisited. Only one mammal is present on Baker, Phoenix, Birnie, 
and Palmyra. The other six islands hare one or more formerly domesticated 
species in addition to the rats and mice. 
Rabbit - Oryctotgus cuniculus - this species is abundant on Phoenix 
but has not noticably reduced the vegetation despite the 
long dry spell. 
Pig - Sus scrofa - this was a common domestic animal on Gardner in 
196>3 and it is possible that a few were left and still survive. 
■ Polynesian Rat - Rattus exulans - on Sydney and the small islands of 
Christmas Island this Is a common species. On Birnie Island 
it is super abundant and may be eliminating the vegetation. 
Rattus sp? - some species other than R. exulans ia common on Washington, 
Palmyra and Christmas. 
House Mouse - Mus muscuius - it is abundant on Baker Island. On Jarvis 
Island it is common having increased with the reduction in 
the number of cats. 
Cetacea - a porpoise skeleton and a small whale skull were collected on 
Sydney and a partial porpoise skeleton was collected on Jarvis. 
Dog - Canis familiaris - kept as pets on Christmas and Washington. A 
few left by former inhabitants are still alive on Gardner, 
and Sydney. On Gardner at least 10 dead dogs were found in 
various stages of decay indicating that they may all die off 
in time. 
Cat - Felis domesticus - present in small numbers on Gardner, Sydney, 
Christmas and Washington. On Jarvis Island only 10-20 cats 
still exist of the 300 plus present in March 1964.
