Alligators in New York

Seventeen alligators, all about four feet long, have been found on New York’s Long Island in the past 10 months, including three alligators turned in at a reptile pet amnesty event in April. New York Department of Environmental Conservation personnel likely never thought they would become expert alligator handlers.

The most recent alligator sighting was in Calverton, NY on Friday. Read and watch the story from Hudson Valley News 12, here.

But this is only the latest alligator sighting on the eastern end of Long Island. Back in May, the New York Post reported on the cluster of alligator sightings and captures. Read that story here. At the very end there is a map of all the sightings.

The NY Daily News did a story on the three alligators turned in at an amnesty day for illegal reptile pets in April. Read the Daily News story here.

Wyoming Expands Moose Study

Non-native tree kills moose in AlaskaThe Wyoming Game and Fish Department and the Wyoming Cooperative Fish and Wildlife Research Unit recently collared 28 cow moose to add to the 65 moose they are already tracking with GPS collars, the Sheridan Press reports.

Twelve of those collars provide real-time data, while the rest will fall off after two years, and will need to be collected so the data can be retrieved, the article says.

The article quotes Wyoming Game and Fish South Jackson Wildlife Biologist Gary Fralick as saying that after the first two years of results, some moose are “very localized,” staying in one spot. Other findings include a low birth rate for the moose, and a rump fat level that compares unfavorably to moose in Minnesota, which are in decline.

The rump fat was measured with an ultrasonograph to determine body conditions. The details are still being worked out.

More Mountain Lions

mo mountain lionWhere are there more mountain lions? There are increases Puma concolor sightings just about everywhere, recent news reports say.

An article in The New York Times focuses on mountain lions’ expansion east from their strongholds in the Rocky Mountains and Texas. The article says that mountain lion sightings are now common in the Midwest, and it includes a map that shows recent sightings, including several in New England.

Read The New York Times article here.

In Arizona, an abundance of mountain lions in the Catalina Mountains has some folks worried about a planned release of bighorn sheep there, says an Arizona Daily Star article. A management plan calls for killing mountain lions that kill the bighorns, although the mountain lions should have plenty of other prey, the article quotes Jim Heffelfinger, regional game specialist for the Arizona Game and Fish Department as saying.

An increase in deer in the area likely lead to the increase in mountain lions, the article says.

Mountain lion populations have been going up in California for at least 20 years, with hundreds of sightings annually, but that doesn’t mean the sight of two mountain lions in Redlands, California isn’t news. Redlands is near the San Bernardino Mountains, east of Los Angleles.

City Life Changes Birds

Euro blackbirdThe bright lights (and noise) of the big city haven’t just made the days of songbirds longer, they have thrown a wrench in the birds’ circadian rhythms, researchers studying European blackbirds have found. The study, which is in the current issue of the Proceedings of the Royal Society B, found that city birds wake up 30 minutes earlier than their forest counterparts and stay up nine minutes later after dark.

When brought into the lab, the city birds still started their days earlier, but their sleep and rest cycles were off.

Early Results in Minn. Moose Calf Study

Moose_CalfLate last month Minnesota Department of Natural Resources researchers collared 49 moose calves within hours of their birth, the Grand Forks Herald reports. Part of a larger study trying to solve Minnesota’s high moose mortality rate, the collared calves were born to collared mothers, a fact that allowed researchers to find them quickly after birth, the article says.

Results have come quickly, perhaps too quickly. Researchers knew that over half of all moose calves die within their first year. But already 22 of the calves, nearly half, have been found dead, mostly from predation by wolves and bears.

The study revealed other surprises. Of the moose that gave birth last month, 58 percent had twins, which was a higher rate than the researchers expected. They also found that the calves started eating plants earlier than had been previously thought.

The article says that the high adult death rate is the big issue in Minnesota, but a low rate of survival for calves is another concern. The 22 necropsies that will be performed on the dead moose calves should shed light on the issue.

Vultures As Pollution Sentinels

Turkey_VultureResearchers from the Hawk Mountain Sanctuary in Pennsylvania have been studying vultures throughout the New World to see if they are effective sentinels for environmental pollutants, such as lead.

The theory, says an Associated Press article that ran in the Havasu News (AZ), is with their ability to eat and digest biological toxins, vultures may be accumulating man-made toxins as well. Testing them for toxins may reveal hot spots that can then be investigated.

A Hawk Mountain Sanctuary blog reveals that they have been at this for ten years. The big news today is that they have expanded the study in to Arizona. The hope is that information from the tough vultures will provide more information on the lead poisoning that is killing the already federally endangered California condors.
