All birds from other parts of the world are possible carriers for disease and potential competitors with native species. In order to keep these diseases out we need to make a list of birds which have the potential to carry disease. All birds imported need to be quarantined and health restrictions need to be placed on all exotic birds imported. There are currently thirty-nine species of mosquitoes in Guam that are all foreign species. So, further introductions of foreign species must be prevented.
All cargo bound for Guam needs to be inspected carefully and sprayed before leaving their ports.
Research shows that the predation of the brown tree snake is responsible for the decline of Guam's birds. It is necessary to cut down on their numbers . The brown tree snake population needs to be drastically reduced in order to allow the recovery of the native birds. In order to find a reasonable solution to keep the brown tree snake from exterminating the kingfishers that would be released, we need to further understand the impact the snake has on Guam. After the release of the kingfishers, further study of both the brown tree snake and the kingfishers need to undertaken.
