The latest bias current estimate is about 50-100 aA, slowly dithering around less than plus one percent of FS, with occasional jumps to about 500 aA or less. I can't tell yet if these jumps are part of the 1/f noise, or line noise and transients getting through the power supplies.

A genetic study published in 2010 ("Genetic evidence for high propagule pressure and long-distance dispersal in monk parakeet invasive populations" - Goncalves da Silva et al. 2010), found that Monks are capable of dispersing up to 100km, which is a huge change from the previous estimate of only about 2 km.

I don't consider myself qualified to estimate the number of so many birds seen, but I'd think it was easily 10,000. It was well worth going an hour out of the way to drive home. Highly recommended if anyone needs a gannet fix in large numbers! Enjoy Spring - Brenda Inskeep Stamford, CT

I Should have added that there has been a very large flight of Bobolinks over the park this year, and yesterday we estimated that there was well over 1000. In fact, they seemed to make up the majority of the migrating passerines. Also, 8 Monk Parakeets circled the park. Quite a few RT Humingbirds moving through as well.

I realize that it's frustrating seeing these birds not doing well, but keep in mind they are a species of Least Concern and have a fairly stable population estimate of 300,000. A couple of additional things I'd like to comment on that have been brought up.

You can't count what you don't see, but I'm still ok with that estimate.  I started 30 minutes after sunrise.  Besides, there were hundreds per hour not counted along the beach, and tens of thousands per hour north of the Oaks.  'And I rarely took a pen to paper.  Here's the breakdown that was recorded. 

The Pew Charitable Trust, a lead player in this effort, estimates that this action will keep an additional 31 million pounds of herring in the water over next three years, which will help the declining population rebuild and provide more essential forage for predators.

A poor, presumably low estimate of 7,000+ finches were seen over the 9 3/4 hours of coverage.  For the first 4-5 hours, there were often flocks at a rate of 10-30 per minute.  Composition of that number is as follows:  4500 Purple Finch, 2000 Finch, sp.(presumably Purple Finch), 100 House Finch, 500 Am Goldfinch, 44 Pine Siskin (mostly 2 afternoon flocks). 

However, they are understudied and are faced with threats which are prevalent around the forest edge of this transitional landscape.We want to estimate large mammal population around the forest edge and understand their interaction with the landscape.
