    24/7 Raspberry Pi/birdNET monitoring

    very interesting thankyou for heads-up on that report ref BirdNET PI - is it possible to change the recordings to 24 bit please ? I tried but failed I tried changing all references in birdnet_recording script from s_16LE to s_24LE to no avail - just get very over saturated outputs

    24/7 Raspberry Pi/birdNET monitoring

    90% sure (checked recording) - BirdNET PI was correct in picking up a Marsh Harrier call today (I've never heard one - seen loads though) so over 4 months its managed recordings of the following raptors: Barn Owl Tawny Owl Marsh Harrier Red Kite Buzzard Kestrel Sparrowhawk pretty impressive

    2 Warbler Sound IDs (Garden Warbler vs Blackcap, Cettis) plus Scoter

    thanks very much for all of the replies -much appreciated. It is very nice (and appreciated) to have these species confirmed (thankyou) as they are unusual/wouldn't have known about without a BirdNET Pi device picking up. The Garden Warbler and Cettis - GW 1 instance of hours of singing but...

    2 Warbler Sound IDs (Garden Warbler vs Blackcap, Cettis) plus Scoter

    wondered if anyone can help me with confirming (or not) these bird recordings please to help improve my bird sound ID. These 3 were picked up by BirdNET Pi which is bottom of the garden - I think they may be correct but I really struggle Blackcap vs Garden Warbler. The Cettis (if checks out)...

    interestingly my BirdNET Pi picked one up yesterday too (I think) - maybe they are on the move

    24/7 Raspberry Pi/birdNET monitoring

    I think this is better representation (first part of clip - with the downturn in tone at end of call) can anyone confirm whether they think this one is Cettis please ? detected twice and sounds like it to me but would be unusual for my garden. First recording is followed by a Blue Tit. One...

    24/7 Raspberry Pi/birdNET monitoring

    I believe BirdNET was correct with Garden Warbler and that my manual listening to confirm (you never know I could be in error too) is also correct I did also check against Merlin

    24/7 Raspberry Pi/birdNET monitoring

    Might well have missed: Lesser Whitethroat - didn't hear myself but recording checks out - never heard in garden before either. Garden Warbler - didn't hear myself but recording checks out - never heard in garden before either. Overflying night birds - Moorhen, Coot, Water Rail - had no clue -...

    24/7 Raspberry Pi/birdNET monitoring

    some interesting Spring Migration Stats for our Garden in Essex Chiffchaff (maybe overwintering one) leading the way, followed by Blackcap (very active now), then House Martins (note March instance not correct, treat 6th April as first actual plot (I saw with my own eyes visiting nest front of...

    Owl or Mammal ?

    Some of the Tawny Owls last few weeks :)

    Owl or Mammal ?

    thankyou and I definitely get what you mean by it sounding too volumous for an owl in the kindly provided link above I listened to all the vocalisations of Tawny Owl and Long Eared Owl (they are meant to be in the village, and I've heard in the next village a few miles away) and none sounded...

    Owl or Mammal ?

    it is but from the house rarely heard or seen in around 4 years, I've heard a Barn Owl once and Tawny Owl once. Although I do see Barn Owls very regularly when driving about the area near dark - I've never seen one from the house - even though I've spent multiple times for half an hour at a...

    Owl or Mammal ?

    I can't be certain but I think would be difficult for a human to make that noise, and it was at 11.20pm - house is at end of a culdesac and there is very little noise at night from neighbours etc. One side of house is right up against field - Mic in the back garden was located by the fence that...

    Owl or Mammal ?

    lol :) - the odd thing is though - I've listened to loads of videos on youtube for dog, deer, fox all sorts of vocalisations and not found something near and don't know how to describe it but the "roundness"/maybe harmonics just sounds a bit more bird like than mammal - although I freely admit...

    Owl or Mammal ?

    I have to admit that was one of my first thoughts - but I've gone through numerous videos online of all of the European Deer (and wider) of their various calls and I can't find anything close

    thanks very much for the link and reply - I wasn't aware of that web book and it's a fantastic resource thankyou for sharing :)

    Owl or Mammal ?

    Recorded last night on a Birdnet Pi - accidentally as it had detected and recorded a Redwing (correctly) - latter part of the recording Its the howl/hoot at the start of the clip. Whatever it was seemed quite close to the mic (which was in the back garden) - very little dog noise at night or...

    birdNET Analyzer model update

    2 questions please (1) what do people find the best combination of recording length, overlap, and "extraction length". I've changed mine to 18 seconds, 0.2 overlap, and 9 seconds extraction - and have changed extraction file format from mp3 (as was very lowbitrate mp3 (64kbps I think) to FLAC...

    birdNET Analyzer model update

    updated my BirdNET-Pi today although made a real meal of it I used the in-built File Manager to delete the old file, and then went to upload to replace but that wouldn't work (maybe upload in the filemanager is restricted) so had to copy into the boot directory (only directory I could access...

    birdNET Analyzer model update

    maybe it is as simple as I thought - please see below some people seem to have had success renaming and copying over https://github.com/mcguirepr89/BirdNET-Pi/discussions/1105

    birdNET Analyzer model update

    yes you are quite correct - it is more complex than I thought thanks to your link though I will see if I can manually update the model on the BirdNET Pi - worse case I can roll back

    birdNET Analyzer model update

    is it just the MData_Model file that has been updated please ? I have a BirdNET- Pi running, can the updated MData_Model (V2) file be re-named and copied over the one on the BirdNET Pi ? I'm assuming the positional data/chance of a type of bird has just been updated rather than any particular...

    Bird Sound ID - Essex - Unable to ID

    24/7 Raspberry Pi/birdNET monitoring

    I will write more when I have the chance - but my BirdNET Pi has completely revolutionised my view of the birds in my garden within weeks I use an overclocked Pi4b (4gb version) with a USB mic, and attached to a 20,000mAH battery I think I get about 18 hours of use/recording an example of how...

    Bird Sound ID - Essex - Unable to ID

    yes by far in the main (although I did mistake one that was a Starling mimicking) - Tawny Owls recorded again last night around midnight a male Tawny Owl calling around 2am a female Tawny Owl calling twice followed by a male replying as I said previously I think this is where these...
