During migration, Scarlet Tanagers, Summer Tanagers, Orchard Orioles, and Painted Buntings all come to the fruit, giving you sustained close looks at birds that are normally too energetic to study well. Don't skip either stop.

What to Expect — Fallout Forecast
April is peak season at South Padre Island and conditions are active. Birds arriving after Gulf crossings — exhausted and hungry — make for close, extended looks as they refuel at water features and fruiting vegetation. Activity tends to be most concentrated in the early morning hours, when new arrivals are moving through the vegetation with purpose.
Migration will continue in waves through late April and into early May. Watch the weather: south winds push birds north quickly and quiet the island, while a cold front or sustained north winds can ground a fresh wave of migrants overnight. Check eBird reports and local birding groups the morning after any significant weather shift — those are often the best days to be on the island.
