    Butorides heron ID, Panama

    Is this a hybrid Green x Striated Heron? I see clear examples of both parental species here in Gamboa, Panama, but I also see individuals that are harder to classify. This bird has chestnut throat stripes and a kind of intermediate purplish-gray neck, as opposed to the buffy throat stripes and...

    Pteruthius Shrike-Babblers

    Okay, I'm a little slow to the bandwagon but I just noticed that Reddy and Cracraft (2007) show the Shrike-Babblers (Pteruthius) as joining Erpornis as two basal old-world members of an expanded Vireonidae. Cool! I wrote a short little bit about this on my blog. My main question here is about...

    Elepaio, Snipe, and Bobwhite

    I was just perusing the Online First section of Conservation Genetics and found a few taxonomy papers worth posting here. I don't know much about any of these systems so I'll refrain from comment. Splitting the elepaio into three species...

    Woodcreepers - Venezuela

    I spent the past several months in the Venezuelan llanos (Guarico state). In my time I saw many woodcreepers and identified all in the field as Xiphorhynchus picus (abundant) and Campylorhamphus trochilirostris (occasional). Then on my return looking through my pictures my friend pointed out a...

    Flufftails

    I just noticed in the new Hackett et al. avian TOL phylogeny in Science, that a Flufftail (Sarothrura) is sister to Heliornithidae rather than being within the monophyletic Rallidae. I looked up Fain et al.'s 2007 'core Gruiform' phylogeny, but they do not sample any Flufftails. Otherwise the...

    Hi all, I've just started feeling this out so I apologize for not doing much of my homework yet... I have a field job in the llanos this fall, and am looking into both a second job to follow it up, and independent birding during some down time. My questions are - how has safety been for...

    Birding southwest pacific in january

    Hi all, I'm heading to costa rica from Dec. 31 - Jan 18th this winter. I'm looking for some advice on where to go. I'll be heading to the Osa peninsula and birding/herping Corcovado with some herper friends of mine for a week. Then I'll split off on my own (unless I convince another birder to...
