Subject: [cobirds] Chico Basin Ranch Banding Station Report- May 22, 2026-Bird Conservancy of the Rockies
Two Spring Seasons ago in 2024 on this date, there was 8-10" of snow at
Chico on the ground. Every year is different and this is not any different.
Spring banding numbers are up from the all- time low bird numbers last
spring that I experienced and numbers are still lower than the previous two
spring seasons. Today the Swainon's Thrushes made their appearance. I was
glad to see them. Last spring they arrived very late and on the last
banding date in May was our biggest catch. Weather definitely alters the
bird's migratory pathways but other obstacles and environmental conditions
can as well. Let's hope for a more normal spring.
Twenty species of birds were banded including 2 more Veeries (Total of 4
banded this spring), and another Ovenbird.
