Flycatcher monitoring for 2025 concludes

Annual territory monitoring along Las Vegas Wash for the endangered southwestern willow flycatcher was completed in August.

This year's efforts identified a breeding pair for the fourth consecutive year at the Wash, with the first nest documented in 2022.

The pair abandoned the first nest, but the female built a second nest and laid two eggs. Sadly, this nest also failed, with both eggs lost to depredation. It was observed in this year's flycatcher monitoring that the pair did not make a third attempt, breaking the two-year streak of a confirmed fledgling at the Wash.

Although not the conclusion we were hoping for, we are already looking forward to the promise of better outcomes next summer.
