    ID help please

    Note that there are hundreds of different species of Lithobius, so I'm not certain of the species ID, but it appears that L. forficatus is one of the most common species in the U.K. and is known as either the Common Centipede or Brown Centipede. Related sites...

    ID help please

    Andy, I hope your bird ID skills are better than your arthropod skills. ;) This is a centipede, possibly a Stone Centipede similar to this one: https://en.wikipedia.org/wiki/Lithobius_forficatus It should be okay to relocate him/her outdoors.

    Is this a Warbler or a Vireo? (Middle TN)

    Thanks for the links. These do show more yellow than I had seen in other photos. It's possible that the blurriness of the photo in this ID thread is causing the expansiveness of the spectacles to be exaggerated, but even taking into account photo artifacts, I still think the spectacles are more...

    Is this a Warbler or a Vireo? (Middle TN)

    By "ignoring" I was referring to the written words in this thread, which until my post had made no mention of the eyering/lores. (Unless you write it down, I don't know what's in your head.) Yes, Pine Warbler has a similar pattern, but looking at more photos online, I haven't found a Pine...

    Is this a Warbler or a Vireo? (Middle TN)

    Everyone is ignoring the most salient field mark (easily discernible despite the bad photo): bright yellow eyering and lores ("spectacles"). No North American warbler has this exact facial pattern. https://www.allaboutbirds.org/guide/Yellow-throated_Vireo/species-compare/64893901

    Cooper's or Sharp-Shinned in Waterloo, Ontario.

    This thread almost makes me long for less-controversial topics like COVID restrictions and mask mandates. For what it's worth, two of the most respected North American field guides, Peterson and Sibley, use the term "streaks" to describe the markings on immature birds' underparts: Peterson...

    Info Needed on Vintage Bushnell Wide Angle

    As you discovered, I created a similar thread that has some answers to your questions. Linking back here: https://www.birdforum.net/threads/questions-about-my-green-rubber-armored-bushnell-8x30-circa-1981.396520/ Yes, they are really a nice little porro binocular.

    Ethical choices in optical equipment

    Of course you are tying to spark a debate. You started with a red herring fallacy (the irrelevant “50 page thread…” premise), propped it up with straw man, righteousness, and card stacking fallacies (a premise you wanted to debate, focusing on hunters’ claim to good intentions while ignoring...

    Ethical choices in optical equipment

    Thank you for posting this. (I've completed the survey.) Coincidentally I've been researching this very topic during the last few weeks and have been corresponding with several optics companies about it. The Cruelty-free Optics site is the most thorough resource I have seen. It covers all areas...

    RSPB ASW 8x40 eye relief question

    The description of the RSPB ASW 8x40 porro binoculars says, "the twist down eyecups mean spectacle wearers can also use these binoculars." But the specified eye relief is only 13 mm (shorter than the commonly recommended minimum of 14-16 mm). Are there any spectacle wearers out there who have...

    Can you identify these binoculars from Jethro Tull’s Stormwatch / “Dun Ringill”?

    I bet you're right. Based on the article "U-boat Binoculars" (http://www.binoculars-cinecollectors.com/U-boat_binoculars.pdf), I think 'C' is almost certainly a German U-Boat binocular. It could be the original Carl Zeiss Jena 8x60 U-Boat Commander's binocular, first made in 1943. Nicknamed the...

    Can you identify these binoculars from Jethro Tull’s Stormwatch / “Dun Ringill”?

    A diversion for the binocular nuts (or anyone else with time on their hands)… Aficionados of fine music will be familiar with the 1979 Jethro Tull album Stormwatch and its cover artwork showing Ian Anderson holding a pair of armoured binoculars: Some might also have seen the video for the...

    Mystery bird print/artwork (late 1800s)

    Rafael, thanks for the research on "Eidographie." It isn't clear to me whether the process described in the article is used for printing on paper. I also found that the English word eidography is defined as "a system for enlarging or reducing drawings." And I found this curious passage from a...

    Mystery bird print/artwork (late 1800s)

    I found this old print/artwork in my grandparents' archives. The text at the bottom reads, "Eidographie, Bourgerie-Villette, r, Fontaine-au-Roi, 56, Paris." I believe "Eidographie" is the type of print, and "Bourgerie-Villette" is the name of the printer (in Paris). It probably dates to the late...

    Questions about my green rubber armored Bushnell 8x30 (circa 1981)

    Does anyone know the eye relief spec for these binoculars? It's not stated in the brochure above and I can't find any other info online.

    questions about Swift Osprey Mark II 7.5 x 42

    Well, I put this idea to the test. I purchased a (roof prism) Monarch 7 (~$480) and... I returned it. To my eye the Monarch 7 created a tunnel vision effect (despite the wider FOV) with significant pincushion distortion at the edges. It also appeared to have a slightly yellow cast (compared to...

    seeking advice on Opticron Traveller BGA 8x24 compact/pocket

    I'm curious about Opticron's new Traveller BGA 8x24 compact pocket roof prism binocular ($329 USD). Initially I was looking to replace my cheap 8x21 pocket Bushnells, but at $329 I wonder how the Traveller's quality might compare to my Nikon Ecobins 10x25 reverse porro compact (~$120) in terms...

    Question about my new (old) B&L Custom 10x40 (Audubon)

    I inherited a really nice Bausch & Lomb Custom 10x40 (armored porro, model no. 61-1046, with Nat'l Audubon Society endorsement badge). I'm curious about the year of manufacture. A couple of other posts on these forums provide approximate years (mid-to-late 1980s), but judging from other online...

    Slightly dark disk in each eye - pupil or glass artifact?

    In my older (1983) 7.5x42 binoculars I have noticed an odd phenomenon: a disk shape that is almost the size of the image field but slightly darker. (See my re-creation in the attached illustration.) The disk is visible in any level of brightness (whether pointing at the sky or an interior wall)...

    Questions about my green rubber armored Bushnell 8x30 (circa 1981)

    Thanks for the info, Binastro. Perhaps the design/shape of these binoculars was based on the [Zeiss] Hensoldt DF 8x30 binoculars, first made for the (West) German army in 1955. A fully-armored version was made from 1959 to 1963. (Source: "Review: Zeiss Dienstglas 8x30 vs. Hensoldt DF 8x30 vs...
