NJ Monk Parakeets

A feral population of monk parakeets in New Jersey has won over some of the populace, but a bill protecting them has stalled in the state Senate committee. Probably because of the high attention that invasive species are getting elsewhere... (News source.)

Kalihi Wallabies

There's an article here on the introduced population of wallabies in Oahu. One correction, the wildlife manager says there hasn't been a documented sighting since 1990, but the Honolulu Advertiser noted a wandering wallaby in 2002.

Burmese Pythons Staying in Everglades

A new study shows that climatic changes are likely to limit the invasive Burmese python to southern Florida. (Eurekalert)

"The results of the models suggest that the pythons are restricted to the vicinity of the Everglades in extreme south Florida, so while wildlife authorities will have their hands full dealing with established populations of these snakes, people outside of Florida should not fear an inexorable northward expansion."

Those California Tarantulas...

The Anomalist notes: "Meanwhile, they haven't announced plans for a survey yet, but state entomologists have already concluded Tarantulas Have 'Invaded' Southern California." Not sure if they realized this, difficult to tell from a blurb, but the tarantulas noted are a native species to North America. (The article mentions a Chilean rosehair, but that's not the species that is swarming San Diego County; it's just noted as a lab worker's pet.) We've got several species of tarantulas in the southwestern states, this just happens to be breeding season.

Now, we do, as noted previously here, have invasive tarantulas in southern Florida. Several years back, some guy down there emailed me to say he had found large black scorpions (either emperors or Asian forests) introduced into one region; but he wouldn't disclose the location as it was his "skunk ape" research area.

South American fish in Southeast Asia


Alien species are found all over. From Vietnam:


"Some fishermen in District 2, HCM City on April 1 caught a strange fish of 60-70kg in a small branch of the Saigon River.
"The strange fish, which is over 1.6m long, has grey scales and red lines across its body, and a black and dark red tale.
"The giant fish was identified by experts as [Arapaima] gigas, which originated from the Amazon River in Brazil.
"This species of fish is considered the biggest fresh-water fish in the world. They eat smaller fishes and don’t harm the environment. With their nice bodies, this kind of fish is bred as ornamental fish.
"Fishermen sold the giant fish for VND40 million (US$2,500) to an ornamental fish breeder in Thu Thiem, HCM City on the same day."

Tegus in Florida

It's common now to see the occasional news article on invasive species in Florida, particularly noting the Burmese pythons and monitor lizards. A recent column by Tom Palmer notes another big reptile has been seen there:

"Wildlife officials have noted another new lizard called the giant tegu, a South American species that can grow up to four feet long. Its diet includes bird eggs, and I've read there's some concern these lizards could invade gopher tortoise burrows and eat anything seeking refuge there except the tortoises.
"So far there are no tegu reports outside of Hillsborough County, but if these large lizards become established, it will only be a matter of time before they spread into Polk County."
