    help needed

    Dig out Harris' MacMillan Field Guide to Bird Identification, turn to page 150 and there's the culprit, with the helpful note - "Partial albino Swift. Such individuals are not infrequent and can cause confusion with rarer species." Indeed.

    Diascope 65 or Apo Televid 77 ???

    A hypothetical question ;) - if you had a Zeiss Diascope 65 with 15-45x zoom, would you exchange it for a Leica Apo Televid 77 with 20-60x zoom?

    Filter - UV or not?

    I want to put a good B+W filter on my scope, mainly for protection. Is there ANY optical advantage in using a UV filter over a plain glass protective one? Thanks.

    Even the guy 'selling' this plan for the FWS, doesn't sound too convinced! http://www.forbes.com/feeds/ap/2007/08/23/ap4049402.html: Fleming said recovery efforts are worth the money even though some have questioned whether the ivory-billed woodpecker sightings were legitimate. "I would...

    According to Birdwatch there is an article in the Wilson Journal of Ornithology claiming that the double raps are perhaps being confused with the wing collisions of Gadwall. http://birdwatchmagazine.blogspot.com/2007/06/another-nail-in-coffin-for-ivory-billed.html

    More from Mike Collins, from 5.15.07 (http://www.fishcrow.com/winter07.html). Watch that space! There's still a long way to go this search season. I have an exciting new idea and will be getting help implementing it. I'm confident that the idea will eventually lead to sightings, good videos...

    I'm still curious as to how LolaGal has seen Golden-fronted and Ladder-backed woodies, neither of which have been previously recorded in Kentucky, and Red-cockaded, which is officially listed as extirpated.

    I see Rosann Kovalcik (Group 5) has her life-vest OVER her Swaros (you can see them dangling out the bottom). Is that in case she's tempted to actually use them?

    Docmartin has a nice piece in his blog today on the paper, media, etc. Answers a couple of points too. And, of course, a bit of humour. ;)

    Yes, Fitzpatrick is citing this as a reason for not accepting Doc's analysis - says it's like comparing apples and oranges. However, the fact that nobody at Cornell is even open to the mere possibility that they might be mistaken is starting to grate on many. Too much at stake I suppose. But...

    Docmartin's paper will be online today. There are already some articles on its contents. See these for a start: http://www.alertnet.org/thenews/newsdesk/N14353338.htm http://www.eurekalert.org/pub_releases/2007-03/bc-aco031207.php http://news.mongabay.com/2007/0314-ibwo.html...

    I seem to recall you also accusing Tom Nelson of being a troll when he posted here (2005), when all he was doing was questioning the evidence that Cornell had presented.

    Was looking over the reported sightings in Florida this season and thought a summary of what has been reported might be of interest: Nov. 2006 Jeff Barna - Flew overhead at treetop level at sunset. Silhouette only. Large woodpecker. Long wings, thin neck, long wedge-shaped tail. Straight...

    Cyberthrush has obtained a copy of Geoff hill's new 'Ivorybill Hunters' and has a mini-review on his site. He quotes Hill's closing thoughts (written before this search season): "What I am sure of is that the ivorybills are there. Not one bird. Not a single pair. At least a half dozen pairs and...

    Boundaries of the Western Palearctic in the Middle East?

    To paraphrase part of the article (but still understandable I hope): Southern border of the Palearctic was established by comparing separate breeding distribution maps of 1,037 passerine species. Maps compiled when working on species texts for BWP from 1987 onwards, but also cover all songbirds...

    Boundaries of the Western Palearctic in the Middle East?

    The 'British Birds' article (Dec 2006) by Kees Roselaar is a good analysis of how the Palearctic boundry has varied, and offers a strong case for a redrawing based on a computer analysis of the breeding distribution maps of 1,037 passerines prepared for the forthcoming 'Handbook of Geographical...

    Mike Collins has been given some private letters of John Dennis Sr which he has been revealing details of. What do folks make of this snippet?: "In a 1985 letter, Dennis mentions that he intensively searched from 1966 through 1970 in South Carolina, Florida, and Texas. Based on this extensive...

    Out of interest, it was Kevin McGowan who first suggested the 'wariness' theory to the Cornell team. Here's his original post from the ID Frontiers list. It was Grizzlies in Colorado that first gave him the idea; however: When I proposed this idea to my Cornell colleagues in 2002, they didn't...

    Talking of recent photos, is anybody going to bid for the photo offered on Ebay? Supposedly a juv. taken in January in Oklahoma. Starting bid of $100. Bargain. :bounce:

    As regards the 1971 photos, one can be seen here. But even some 'believers' admit they are not conclusive. In the same article Van Remsen says: They are lousy photos, taken with a Brownie Instamatic camera. The photos remain unconvincing to many people. You can’t rule either way, fake or real...

    Tmguy has taken his site down, but the photo is preserved in all its glory on the Birding is Not a Crime blog. Tmguy posted this on the 'believers' forum recently, on the impossibility of mistaking a perched IBWO!

    Maybe you should blame the Cornell Lab, since the information appears to have been gathered from there, who in turn claim to have used the following as their source of information: Robinson, T. R., R. R. Sargent, and M. B. Sargent. 1996. Ruby-throated Hummingbird (Archilochus colubris). In The...

    Probably because we haven't memorised every single IBWO post. And, believe it or not, what might be 'obvious' to you may not be to others. Just one example where you feel what was written in an article was 'twisted' is not too much to ask is it? Or are you unwilling or unable to do that? And why...

    Can't you give us an example of this 'twisting' rather than have us searching through pages of posts?
