No matter how the Eurasian Tree Sparrow ended up in the town of Neah Bay, the new additional mystery is perhaps how long has it been there?!! Visiting California birder, Steve Hampton, has nicely captured photos on November 10 of what is near certainly a House Sparrow X Eurasian Tree Sparrow hybrid. Check it out at this link to Steve's eBird submission on the 10th.
This bird is somewhat similar in appearance to the pure bird, but as Steve points out the apparent hybrid has a gray forecrown, less pronounced dark cheek spot, and more pale in the lower mandible. It does sure seem most plausible that local breeding took place for such a result.
It would be nice to see if we could gather a bit more possible photographic evidence of this hybrid or even if there are other hybrid individuals. Birder's that took photos the last couple of weeks or months give them a look-see and report back if you have something of interest. And, those heading to Neah Bay in upcoming days or weeks, be on the look out. I know, it is not all that often that we pay a great deal of attention to House Sparrows!
