[Tweeters] Osprey Catches Flounder...

[Dennis Paulson]

Several of us have watched Ospreys at length in Everett, and the most common fish they bring to the nest is the Starry Flounder, Platicthys stellatus. They are indeed bottom fish, but I think they occur in very shallow water. They are very common in our waters.

I have hardly ever seen them catch anything other than flounders. Of course as one can tell at low tide, the water at Dumas Bay and at Dash Point SP is quite shallow. Then again it will depend on how far out they were fishing Tom. It does raise an interesting question as to how deep an Osprey will dive?

We finished the survey, then decided to wait a bit in hopes that they might make a dive and catch something. We were paid off in less than 10 minutes as one of the raptors dove deep and pulled out a medium sized Flounder. It took awhile to gain altitude after surfacing.

I’ve researched this behavior a bit and find that it is documented, even underwater filmed, so it’s not uncommon for them to catch bottom dwelling fish. It’s possible that the water depth at Dash Point SP was just 2-3 feet I guess. I can’t imagine that the bird could go much deeper than that. Anyhow, it was a spectacular display.
