When to expect prothonotary warblers in Louisiana

Prothonotary Warblers are summer residents in Louisiana, arriving shortly before nesting begins in March and leaving after the young are independent.

Humid subtropical, with coastal marsh, bottomland hardwood forest and piney uplands in the north.

Nesting in Louisiana

Across Louisiana, prothonotary warblers typically nest from March–June. Plan around that window: February for setup, June for clean-out.

Very hot, humid summers and hurricane season June–November.

  • Have boxes cleaned and mounted before February — prothonotary warblers begin prospecting ahead of egg-laying.
  • Use a 1 1/8 in entrance on a 4 × 4 in floor, mounted 3–6 ft over water.
  • Fit a pole baffle or hole guard; ventilation gaps and drainage holes are essential.
  • Clean out old nests after each brood and again after June.
