Hi,

They are probably a species of beach hopper (
https://www.netartsbaytoday.org/html/beach_hoppers.html).
Beach hoppers are amphipod crustaceans that can live out of water. They
don't fly, but they "take off" with hops. They hop by tucking their tail
under their body and quickly flicking it out, hurtling them into the air (
https://www.wildlifetrusts.org/wildlife-explorer/marine/crustaceans/sand-hopper).
OIMB has student projects for learning about their jumping (
https://oimb.uoregon.edu/Documents/GK12/GK12-Second-BeachHopperIntro.pdf).

They can be quite numerous, and other shorebirds also go after them.
Sometimes they are mistakenly called sand fleas.

In the top photo, the beach hopper's two antenna are pointing downward as
it is upside down in that hop.

One day at a time,

Range Bayer, Newport, Oregon.
