Warbler Guy, I heard about you overseas and I'm coming to the USA to find warblers in May. Which warbler field guide do you recommend?

Norman (in England)......There's two essential field guides:

1. The Warbler Guide, by Tom Stephenson and Scott Whittle, Princeton Univ. Press, 2013

It's an exquisite, comprehensive treatise that hosts a dizzying array of excellent features that will edify both beginning and advanced warbler watchers.

Beyond the typical features hosted in a field guide, The Warbler Guide format highlights new ways to identify species via clever comparison photos; close-ups of body parts not usually shown in field guides; information to age and sex individual birds; "quick ID" pages to reduce the steps to identify an unknown species; and much more.

You won't be disappointed in ordering this field guide that is easily obtained at amazon.com,
americanbirding.org, and several other online bookstores.

2. Warblers, by Kimball Garrett and Jon Dunn, Houghton Mifflin Publishing, 1997

As a complement to The Warbler Field Guide, Garrett and Dunn's field guide remains a masterpiece.

Although some information and map-related data is outdated and/or needs updating, this
amazing field guide remains one of the finest bird-specific publications ever created.

I'll write more about this guide soon.

For now, suffice to know: Buy this field guide....and, better, buy both of the aforementioned.

With these two publications, warbler enthusiasts are well endowed with the best bedtime reading they could imagine.

Warbler Guy, I know it's not recent news, but what happened with the most recent scientific warbler name changes?

Good question, Vinny.

Here's a Share And Tell courtesy of The Carolina Bird Club (https://www.carolinabirdclub.org/brc/aouchanges.html#aou54) whereby the 52nd Supplement,
July, 2011 to the AOU Checklist of Birds addresses your question and others related to the wood-warbler family:

There are major changes within the wood-warbler family (Parulidae), consisting of many reassignments of genus and a new linear sequence of genera and species.

• Genera Parula, Dendroica, and Wilsonia are deleted by being lumped with other genera. Parula and Dendroica are lumped into Setophaga. One species of Wilsonia (Hooded Warbler) is also lumped into Setophaga, and the other two species (Wilson's and Canada) are lumped into Cardellina (the genus of Red-faced Warbler).
• Kentucky, Mourning, and MacGillivray's Warblers are moved to genus Geothlypis (same as Common Yellowthroat) leaving only Connecticut in Oporornis.
• Although the genus Parula no longer exists, a provision of the Code of Zoological Nomenclature allows the family name to remain Parulidae.
• The new sequence of species, with new generic names, is:
