Black-and-White Warbler
Mniotilta varia

Superficially similar to Blackpoll and Black-Throated Gray Warblers, the Black-and-White Warbler’s foraging behavior is more like that of a nuthatch. While we see most warblers foraging among the leaves and flowers in the tree canopies, this bird makes its living looking for invertebrate prey hidden in the folds of tree bark.
Rare to uncommon in the western USA, this bird’s expected range is in eastern USA and Canada. Unlike most of its warbler cousins, the Black-and-White Warbler’s genus (Mniotilta) survived the sweeping reclassifications of 2011.
Until I traveled to Texas, both of my meetings with this species were in my Southern California yard. These birds are a rarity on the West Coast, and had it not been for the pictures I took, I might have been accused by local birding experts of mis-identifying this warbler (I’ve had that unpleasant experience on more than a few occasions).
In Texas, the meetings I enjoyed were many; they were almost commonplace in the early spring migration. South Texas and its Gulf Coast zone hosts Black-and-White Warblers through winter, and I found them to be common in many of the places I birded when I returned there early in 2021.
Today, science regards the Black-and-White Warbler as monotypic (i.e. no subspecies).

Black-and-White Warbler(Mniotilta varia) |
Description: Black-and-White Warblers forage like no other warblers. While most warblers look for insect prey among the leaves in trees, these birds probed crevices in the bark, like nuthatches. The Convention Center on South Padre Island, Texas is a first rate birding destination. I spent several hours in the morning and several more in the afternoon on this day. |

Black-and-White Warbler(Mniotilta varia) |
Description: After my morning at the rookery, I walked some of the sanctuary trails and found this warbler. I camped on High Island (Texas) a half mile from the Smith Oaks Sanctuary, where among its 177 acres is a large pond hosting a rookery for egrets, spoonbills and cormorants. I spent my Saturday morning there and returned for another visit in the afternoon. |

Black-and-White Warbler(Mniotilta varia) |
Description: Having spent the winter here, this warbler will soon leave Texas and head north. Last year the global pandemic prevented me from experiencing the full effects of spring migration in south Texas. This year the gates are open and I’m venturing to South Padre Island about every second day. |

Black-and-White Warbler(Mniotilta varia) |
Description: Black-and-White Warblers have been here all winter, but by now migrants are showing up as well. Sunday was a day when the birds and then birders increased their respective presence on South Padre Island. Both are to be expected as spring migration steps up the bird numbers moving through on their way north. |
