Local entomologist Dr. Aubrey Moore says the theory is mass amount of spiders is caused by the brown tree snakes picking off the birds. He told KUAM News ...
This is an image of an invasive vine growing in Mongmong. The owner of the land that it is growing on is concerned because this weed is starting to spread. He contacted the Guam Department of Agriculture for advice and was referred to the University of Guam Cooperative Extension Service.
Responding to a request for identification based on the above image, Lauren Gutierrez responded:
"I believe this vine is Tinospora crispa (L.) Hook. f. & Thomson. I have found this in the Matgue river area also. Another Tinospora, T. cordifolia was also seen in Toto. T. cordifolia is considered a medicinal plant but where we saw it growing it was very invasive. We have an endemic Tinospora, but the stem is smooth and is found along western coastlines in Agana thru Asan."
Lauren has a great image of Tinospora crispa forming an impenetrable thicket.
Armed with the scientific name, I was able to search for previous reports of this weed on Guam. My search turned up one of my own blog posts from December 2008:
This antmimicking spider was dropped of at my office for identification. An interesting feature of his mimick is the extremely reflective patch of white hair on the cephalothorax which makes the spider look like it has a "neck".

Aubrey Moore is interviewed by Louella Losinio concerning the recent spider article published by Haldre Rogers, Ross Miller at al.
Ernie Matson made the attached recording made by an unkown critter in his back yard. I don't recognize this signal but I suggest it is probably made by a gecko or an insect. If it is an insect, it could be caused by an insect feeding (a boring insect), or an insect communicating by stridulation.
