Yesterday an immature Northern Shrike was observed at Exton Park by multiple birders. It appeared to be the same bird as reported in eBird back on 02/25 and not seen/reported again until yesterday. The bird was still present this morning making an appearance for 5 to 20 minutes or so and then disappearing into a tangle somewhere for a half hour or more. Although I've seen Northern Shrikes multiple times this is the first time I've heard one singing and calling.
