Was walking along the columbia river, heading east, around 5:30pm on 4/30/20. noticed a few hawks circling, as well as an airplane from pdx. because i was looking at the birds, i also noticed a smallish swarm of around 10-20 small white orbs dancing around in the sky. they appeared about the size of golf balls, but had to be much bigger because of how far away they were. clear skies except for a few clouds, sunny. watched them, & had my daughter confirm what i was seeing. she saw it as well. i think it scared her. we were watching in disbelief for about 2-3 minutes, when the orbs slowly vanished, or became invisible. tried taking a video, but it wasn't able to pick up such small orbs. it lasted about 5 minutes all together. i did see some pics from texas on this site, of exactly what i saw.... they were zooming around each other in a very un-drone like way... kind of like how fireworks sometimes shoot & zoom around each other, but it was obviously not fireworks. if i can clarify the video somehow, i'll post it.
