Tucson Audubon Society: Southeast Arizona Birding Festival – Arivaca Lake and Buenos Aires NWR Field Trip

We will explore Arivaca Lake and some areas of Buenos Aires National Wildlife Refuge such as Aguirre Lake.  Locations and order will depend on overall and recent monsoon activity.

Aguirre Lake always has some water and can be a shorebird bonanza during good monsoon years when the lake fills. Arivaca Lake was the hottest hotspot of the year in Pima County last year and always has potential for rarities. Yellow-billed Cuckoos, Thick-billed Kingbirds and Gray Hawks are regular summer residents and Varied Bunting is expected most years. Based on scouting other short stops will be made in Buenos Aires NWR or Arivaca. Limited to 9 participants.

  • 5:00am – 1:00pm
  • $65/person + Festival Registration
  • Difficulty: Difficult. (Some walking on steeper slopes with loose rock at Arivaca Lake. Open areas with high exposure. Drive time to location about 90 minutes)


Van Trips depart from the DoubleTree by Hilton Hotel at Reid Park.
