Nice, I think I'm getting it but have become a bit of a technophobe since we last met!
It's essentially three elements.

Parabolic Reflector
Microphone (Any mic will fit in the Parabolic you suggest?)

How do you position it? I do have a few trees on my property over 60 feet but I don't fancy that. Is it ok just outside on a tripod?

Looking forward to this. My Garden list stalled in the 90's. Not the decade obv!

Luv Dave
Any Omni-directional mic will work in the parabolic - but the mic is where to spend your money. I usually open my office/seawatch hide window and point the parabolic upwards and out a bit over the beach. This has the advantage that the recorder is inside and can be powered.

You need some software too - I recommend Audacity and Raven [from Cornell] I use Audacity to listen and make quick assessments on sonagrams, isolate calls I want to look at further and cut out noise, whilst Raven is better for producing final sonagrams

In other news there was a Yellow-browed Warbler in ther back garden yesterday afternoon

This is a play through on audacity, using windows 10's recorder to capture a video.
Jan 1st 2020.
30 species recorded today, unsurprisingly 30 for the year. 42 birds caught, 15 of which were retraps.

The biggest surprise was a nominate race Chiffchaff which was caught in the front garden, in the buckthorn. Chaffinch and Goldcrest were also likely migrants.

A sound only Raven 4 Brent Geese, viewable down the mist-net lane and 200 or so Pink-footed Geese were the other highlights
After days of gales and lashing rain, it was a little calmer and brighter today.

2 adult Little Gulls, around 150 Kittiwakes and a Razorbill was new for the year [53 species]

There was a Great Northern Diver on Jan 25th as well as regular sighings of Chiffchaffs
Up to 61 species now this year with the surprise capture of a Tree Sparrow Yesterday. Never common on North Wirral, these species is declining markedly, so I was less that 50:50 about recording one this year, let alone ringing one.

Also new were Wigeon, Jackdaw and Rock Pipit.

A Fulmar Feb 23rd was unexpected.

In January I rang 85 birds of 15 species, but only 10 of 6 species in February.

I am doing a patchlist - so will endeavor to keep this up to date.
Long-tailed Duck, 6 Gannet and 6 Brent Geese was the highlight of January 1st.

5/6 Long Tailed duck a single then 5 in flight with Raven and Guillemot new for the year

Too many Scoter to count today - 10-30K at a guess, 110 Brent Geese, Wren and Pied Wagtail new for the year. 45 Red-throated Diver and 210 Great crested grebes as a result of boats in the windfarm (probably the cause of more visible scoter too.

39 for the year
