Re: [nfc-l] [nysbirds-l] Minimal Migration or Population Decline?

[Laurent Fournier]

Hi Laura

Interestingly enough, I did the first round of my annual survey of a large
park in Ann Arbor (SE michigan), and had an unusual 3 pairs of scarlet
tanagers, instead of the usual one.

Not a very good sample size, admittedly

Re: [nfc-l] Gray-cheeked Thrush Examples

[Laurent Fournier]

I second Laura. The old bird website has tons of warblers and sparrows NFC,
but I would love to have more thrushes NFC.

Swaisson, Wood, Veery, Hermit Thrush, anyone?

Re: [nfc-l] roll call!

[Laurent Fournier]

I am just starting here in Ann Arbor, Michigan (South East Michigan). I
mean really starting, as it is my first season.

I agree it could be fun to create a map of all the listening stations in
North America!

[nfc-l] hardware question from a beginner, recorder, preamp, etc

[laurent fournier]

Hi All

I am currently in the process of building the "flower pot mic" described in the 
"oldbird" website. 

2 questions : 

- any tip about which preamp I should use? (does everyone uses one?). The old 
bird website only mention the Rolls MP13 preamp ($70 on Amazon.com), but I 
noticed others available for a much lower price ($20). 

 
- Does everyone here does their own recording using a laptop, as suggested in 
the oldbird? Does anyone use a digital recorder, and later transfer their files 
on their computer for further analysis?


Any comment or advice would be greatly appreciated!

 
Laurent in Michigan
