We got the scoop from some local bird observers…including the coast’s Range Bayer…
1) At 8:30-9:00 AM this morning (9/27), Betty Bahn counted about 20
“light brown” dragonflies per minute flying “generally south” at her
house in Yachats, out to the Yachat’s State Park, north to about 4th
Street. Wind is moderate from the SE.
2) At 9:15-9:45 AM this morning, Chuck Philo observed a a small flight
of about 3-4 “little red” dragonflies flying south . He was along the
Yaquina Bay South Jetty road near the outhouses. Interestingly, there
were many perched on the grass as if poised to take flight, and Chuck
tried to take pictures of them.
About 30-40 ft overhead there were many California Gulls circling and
hawking flying insects. They may have been catching flying ants.
Dragonflies here typically fly up to 20 ft above the substrate, so the
gulls probably were not feeding on dragonflies. In previous years, no
one has definitively observed a gull taking a dragonfly in one of
these mass flights.
3) At 9:45-9:50 AM this morning, I saw no dragonflies during a 5.0
minute watch at 717 SW 6th Street in Newport. This is about one block
from the ocean and is a location where mass flights of dragonflies has
sometimes been noted in the past. There were also no gulls circling
and hawking insects or any indication of any flying insect swarms.
Mass dragonfly flights have been noted in association with winds from
the east in late August-early Oct. in past years.
