Abstract—We documented between-winter site fidelity of orange-crowned warblers (Oreothlypis celata) in the Lower Rio Grande Valley of Texas, between 2004 and 2017. Overall, we recaptured 13.9% of the 201 banded birds in ‡1 subsequent winter season: 20.8% of the 101 birds banded in urban natural areas, and 7.0% of the 100 banded in rural areas. We recaptured 8 birds ‡3 winters after their initial capture, indicating extended winter site fidelity.
