I biked over to nearby Powderhorn Park this evening, searching for the Summer Tanager with two other birders.
We all looked for over an hour (5:00-6:15 in my case) but, as of when I left, couldn't relocate it.
We did find the male Scarlet Tanager and swarms of warblers. So it sure "felt" like it was there -- at one point I even thought I heard two weak "pikatuk" calls.
Perhaps others can find it! Beautiful photo Jonathon!
Since I've never seen a Summer Tanager before and since I'm not very
familiar with molting scarlet tanagers, I'm not 100% certain on this ID,
but at around 1:30 this afternoon I spotted an adult male Scarlet
Tanager with what I think was a First-spring male Summer Tanager at
Powderhorn Park in south minneapolis. Here's a couple photos -- I'm
sure if I got the ID wrong, somebody will tell me soon enough :)
