Good question, Christian (in Dallas, TX)….According to several citations noted in Birds of the World (Birdsoftheworld.org), many species of wood-warblers perish in their first year of life, with the average lifespan 6-10 years….BUT I recommend looking at the following article to see the range of some wood-warbler species’ age ranges: Longevity records of North American birds: Remizidae through Parulinae (Klimkiewicz, M. K., B. Clapp, and A. G. Futcher (1983). Journal of Field Ornithology 54:287–294)….and accessed via: https://nwrc.contentdm.oclc.org/digital/collection/NWRCPubs1/id/20856

Amazingly, a Yellow Warbler was documented to live at least 11 years based on banding records (i.e., a banded Yellow Warbler was recaptured, so field biologists were able to determine its age).

Meanwhile, it’s time to see our local West Coast wood-warblers….yet I’m also looking forward to pursuing sightings of vagrant wood-warblers at the Outer Point within Point Reyes National Seashore. I’m lucky to live only 40 minutes away….though when I visited today, the dense fog prevented perusing the Monterey Cypress trees where vagrants tend to be seen from mid-August through October annually.
