[Tweeters] I-5 Bridge nest

[Martin Muller via Tweeters]

David, Tweeters,

In the past I’ve spent many hours staring at the underside of the I-5 Ship Canal Bridge, especially when (in the past) Peregrine Falcons nested there.

The only three species of birds (other than the falcons using a box placed on the bridge in cooperation with WSDOT) I’ve found nesting there were:
1) European Starlings. They would carry grasses into holes in the metal structure (beams) to build their nests out of sight.
2) Rock Pigeons also nest in nooks and crannies of the bridge, but I’ve never seen them use a visible stick nest.
3) American Crows were the only birds I’ve ever seen using a stick nest under the bridge (there are multiple, all well-away from the falcon nest box - which hasn’t been used in years-).
So that would be my guess. And a guess it is, since this is not nesting season (except possibly Rock Pigeons which are known for nesting year-round in our “mild” climate).

Happy new year.

I was walking under the I-5 Bridge yesterday on the south side of the Fremont Cut and noticed what looked to be nest high up in the infrastructure of the bridge.

Any thought on who would be nesting there? I can send a photo if anyone is interested.

Thanks kindly,
David
