Songbirds along the New England coast – including in nearby Westport, Conn. – have been found to have elevated levels of mercury. The toxic chemical can affect humans and wildlife and has long been known as an environmental contaminant.
Freshwater fish are a well-known reservoir of mercury. The salt marsh sharp-tailed sparrows that were studied had mercury levels well above the levels found in loons and bald eagles, which feed on such fish. Researchers from the Biodiversity Research Institute in Maine said the study showed mercury wasn’t just a problem limited to freshwater areas and birds that eat fish. The sparrows eat seeds and insects.
It also points to the need for a national mercury monitoring program, which is being pushed for by Sen. Susan Collins, R-Maine. Sen. Hillary Clinton, D-N.Y. has signed onto the effort.

We’re on a first-name basis with the moon in my house. Her name is Luna. If you have small children, you will know that comes from the television show “Bear in the Big Blue House.” Bear ends each show by stepping out onto his balcony and recapping his day with Luna.
At home, we don’t talk to the moon but we have been enjoying the large moon rising each night this week as the sun goes down. This month’s full moon (two days ago) is known as the Green Corn Moon.
Then there was this week’s lunar eclipse. I didn’t witness it but if anyone wants to supply a review, feel free to add a comment. Here’s a news story from Australia that features video. MSNBC has a good, online round-up of the event.

Thieving birds. That was my thought after spending Monday on a Rhode Island beach. The photograph shows a gull who knows what kind of snacks he likes. The bird grabbed a small bag of something – potato chips, cookies, who knows – from someone and managed to open the package. 
That was an interesting feat to witness. But a little while later, one of his feathered colleagues swooped down and plucked half of a ham-and-cheese sandwich (on a roll) OUT OF MY WIFE’S HAND. It happened so fast that no one could warn her about the impending pilfering.
Of course, the whole thing led to a related thought about Alfred Hitchcock and his angry-avian-centric movie.
According to SeaWorld (of all places), some species of gulls exhibit a characteristic called kleptoparasitism, which means they steal prey (food) from other birds.
Here are some facts about ring-billed gulls, many of which hang out in the Lower Hudson Valley’s parking lots, ball fields, etc.
While we’re on the subject of sea-related birds, check out this story on cormorants in yesterday’s NYT  which, in keeping with a summer-related theme, could be titled “Where the Birds Puke.”
