No (R)egrets

A short while ago my friend Eric and I were doing some light, casual, local birding. We managed to find a Multnomah County Swamp Sparrow a new county bird for each of us (both #215!).

Then a report of a Cattle Egret came in. A week prior there was a report of one at Fernhill Wetlands that turned out to be a Great Egret. But this report seemed more plausible, “seen with 10 Great Egrets.” We didn’t see photos, but we also didn’t have a good reason not to try for it, so we went.

Two hours later we were on the side of Washburn Lane scratching our heads. Is that egret smaller? Maybe that one? None looked strikingly different. They were also difficult to see due to tall grass and poor light. Then two egrets flew and one looked “slightly smaller.” Sort of. See Eric’s photo of the egrets in this eBird checklist.

We left knowing we hadn’t seen a Cattle Egret, but we weren’t sure if the bird we saw was a female GREG (males can be 20% larger than females) or young egret or something else.

My only usable photo of egret sp. with nothing for scale

Turns out, this egret sparked debate that it could be an Intermediate Egret, a medium-sized egret that occurs from Africa to the Philippines. There has been a single confirmed occurrence of an Intermediate Egret (found deceased, blown in from a storm with 7 other egrets) in the Aleutian Islands on Buldir Island in 2006. So the likelihood of this bird being Intermediate is (sure, anything is possible) slim.

I feel it’s similar to the McKay’s Bunting “pale bird,” without a DNA sample we’ll never know for sure. To distinguish Intermediate from Great Egret, Oriental bird specialist Desmond Allen says “after the first 500-1000 you may start to see the differences more easily.” Sounds like a fun (painful) I.D. exercise. I didn’t know Intermediates existed before this, but for now I’m leaving this one as egret sp.

Eric and I gave up egretting to take another look at the Tundra Bean-Goose nearby at Finley NWR. Eric spotted the goose easily and we got the best looks yet.

By then it was nearing dusk so we left to look for Short-eared Owls at Prairie Overlook. We saw two! Along with Red-shouldered Hawk, Rough-legged Hawk, and distant looks at a White-tailed Kite. Excellent consolation birds all of which I took terrible photos of.

Guess who

Four days later another Cattle Egret report came in. What?! This time I waited to see photos and sure enough, James Billstine had found two in Tillamook! It was noon and I was at work, but I knew if I left immediately I could make it before dark.

Finally, real Cattle Egrets! Distant looks, but still a good reminder how tiny they are compared to Great Egrets. No question about these (state year bird #319!). Maybe someday these two will make even more Cattle Egrets in Oregon.

No regrets.
