    Affordable thermal device that comes with a screen?

    That sounds great, thanks! Would be very happy to hear more news if you happen to play around with the device more 😁

    Affordable thermal device that comes with a screen?

    Ah, you were referring to the battery of the phone and not of the camera!! I assume that means the camera itself doesn't require any charging?

    Affordable thermal device that comes with a screen?

    Hi Torchepot Thanks for the various details! The battery life seems a little short, not quite sure if 3 hours will be sufficient for owling sessions...how is the camera charged, and is it possible to use it while charging it with a portal battery? Also have you encountered any problems so far...

    Affordable thermal device that comes with a screen?

    Ah, that's a bummer! I hope the refund and the second purchase goes well... The Youtube videos make the product look amazing, I think (hope) it'll perform well for birding too.

    Affordable thermal device that comes with a screen?

    Oh I didn't even know that was possible! Thanks, that's great to hear, opens up more options. Looking forward to your updates 😃

    Affordable thermal device that comes with a screen?

    About a year ago I had the chance to use a thermal monocular (Pulsar Helion I think) but it made me dizzy within minutes. I'm fine with binoculars, but generally can't handle even ordinary monoculars. The experience put me off using thermals for birding, but I was recently able to play with an...

    Question about post-processing: quiet birds suddenly screaming

    Hi Stein, when you say levelling the loud and low bits, does that mean normalising different parts of the recordings to -3dB (or whatever value) respectively? Am a little puzzled because wouldn't that, as you shared, cause the background noise to fluctuate accordingly? Also wondering why that's...

    So I got myself a Tentacle Track E

    Title says it all. I recently purchased my first personal sound recorder in the form of a Tentacle Track E. When searching for mic and recorder recommendations I trawled through BirdForum and xeno-canto, thought I'd start a simple thread for anyone who is considering this device. Am just an...

    5 Days in Singapore: Best Birding Places

    Pulau Ubin is a reliable place for Oriental Pied Hornbill (and there's a single Black Hornbill mixing with them you might chance upon) and all of Singapore's sunbirds can be found there (especially Copper-throated Sunbird at the mangroves, and the rare Ruby-cheeked at Chek Jawa).

    Question about post-processing: getting audio-bombed

    Thanks again Jon for the highly specific advice. So much to learn! I've seen large white bands on sound clips online (and am myself guilty of contributing some) and at times find them somewhat inevitable, especially for birds like doves that are soft and at low frequency that everything else -...

    Question about post-processing: quiet birds suddenly screaming

    Thanks for the advice Jon and Mono. Hmm I see, quite context dependent as shared by the both of you. But okay it does make sense that I shouldn't artificially reduce/increase the amplitude of respective sections that would distort different vocalisations' respective volumes! What's the general...

    Question about post-processing: getting audio-bombed

    Thanks for the detailed advice Jon! I post-process via Audacity which too has copy paste functions, will use them next time to remove loud clicks/other human noise. Seems a little bit like cloning in Photoshop, it'll probably take me a little bit of pratice to make things sound smooth for...

    Question about post-processing: quiet birds suddenly screaming

    Sometimes when recordings birds - usually when targetting the (presumed) contact call of a foraging flock - one or two individuals would have sudden outbursts of loud songs/calls, only to return to their contact call again after a few bouts. This causes problems when normalising the sound...

    Question about post-processing: getting audio-bombed

    When recording a focal species I sometimes get "audiobombed" (like photobombed but audio) by various factors, but generally due to 1) Digital/actual noise. Digital ones being unexplained interferences resulting in sudden loud clips, and actual ones when a fruit/leaf falls and makes a loud...

    Chestnut-cheeked Starling? Singapore

    Yeap! My personal opinion is that the odds are against it being from a cage, though.
