The Willows is a smallish (47 acre) park surrounding an old mansion in Radnor Township in the north part of Delaware County, Pennsylvania. It isn't right close to me, but it is a quick drive up a main road to get to, so I've been going there every now and then birding.
Just like Taylor Arboretum near me, The Willows is one of the eBird hotspots that is dominated by a single person's listing effort (with Taylor dominated by my listings), with one person birding it many times in one week (I bet it is during her lunch break or something). It is at both times an underutilized and well documented spot.
So when I saw that there were some warblers spotted in it the other day, I had to stop by and get myself my first Palm Warbler of the season. I also had to try out my new camera! (Yeah, those warbler pictures sort of suck...I'm just learning about my camera and learning how to imbed pictures from Flickr).
