Northern Barred-Woodcreeper
Many birders hear the word « woodcreeper, » they picture the Brown Creeper of North America or the Eurasian Treecreeper. But in the Neotropics, woodcreepers are a completely different lineage of birds. Rather than being closely related to the treecreepers (Certhiidae),
they’re actually members of the ovenbird family (Furnariidae), where they evolved independently
to fill a remarkably similar ecological role. It’s a good example of convergent evolution.
Mexico is home to 11 regularly occurring species of woodcreepers, ranging from the tiny Wedge-
billed Woodcreeper to the impressive Strong-billed Woodcreeper. The Northern Barred-
Woodcreeper is one of the largest. Together, these species occupy different habitats and forest levels, each specializing in its own way of finding food.
Powerful and methodical, the Northern Barred-Woodcreeper moves effortlessly up massive tree
trunks, using its stiff tail for support as it searches beneath bark, in bromeliads, and among epiphytes for large arthropods. It will also occasionally take small lizards. Like several other
tropical forest birds, it often follows army ant swarms, taking advantage of the insects and other small creatures flushed from the leaf litter.
The Northern Barred-Woodcreeper (Dendrocolaptes sanctithomae) is one of the true specialists of the Neotropical forests.
