    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...

    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...

    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...

    Record Committees and record keeping rules

    I'm a new member to the local Bird Records committee together with several other folks. We're all in our 20s and have only been birding for ~6 years while others in the committee have tons of experience, many with their bins before our parents even met. That being said we're hoping to improve...

    Sharp-shinned vs Cooper's Hawk, California

    Hi all, A question that has been asked a million times before I'm sure. Was looking through some old pictures and a bird I identified once as a Cooper's looks more like a Sharp-shinned to me now. ID reasons: Small head unlike Cooper's which should have a bulky and bigger looking head, thin...

    Phylloscopus, Thailand (with sound recording)

    A phylloscopus warbler photographed at Sab Sadao, Thailand. Despite getting a sound recording and comparing it against a bunch of songs/calls of the possible phyllocs in Thailand (I admit I have not listened to every single clip), I still can't find a good match. Call ((sub)song?) at...

    Cyornis (Blue Flycatcher), Khao Yai, Thailand, 2

    Cyornis (Blue Flycatcher), Khao Yai, Thailand

    A female type Blue Flycatcher photographed at Khao Yai National Park, Thailand, January 2020. Altitude of about 700 metres. I managed to get a recording of the call and song (https://www.xeno-canto.org/519993 and https://www.xeno-canto.org/519995 respectively) but am still struggling to nail...

    Cooper's or Sharp-shinned?

    And so once again, a Cooper's vs Sharp-shinned predicament. I've not positively seen the latter yet, and thus can't comment much on the size of the bird. These are the only two photographs I have. The tail seems "notched". There's some white tip, but from what I've read on other forums, it...

    Flycatcher identification - Doi Lang, Thailand

    Hi all, I would like to seek help for the identification of this flycatcher from Doi Lang, Thailand, photographed in December. The shape looks like a Ficedula, I am guessing female Slaty-blue Flycatcher from the whitish throat?

    Kingbird at Arizona

    Hi, I photographed this Kingbird at San Pedro Riparian National Conservation Area, Arizona, United States of America on 14th August 2018. Is this a Tropical Kingbird? Here are my reasons. 1. Bill clearly not thick enough for Thick-billed, head not dark enough for Cassin's. 2. Slight green on...
