Yesterday morning’s walk at Frick Park had great weather, lots of participants and good birds.

Early in the walk we encountered horsenettle (Solanum carolinense), pictured above, whose flowers are similar to those of its relatives in the Solanaceae or Nightshade family including tomatoes, potatoes and eggplant (called aubergine in the UK). Though it’s not a nettle, its common name refers to the thorns on its leaves. Did you know the leaves smell like potatoes when crushed? Thorns prevent me from trying this.(*)

Best Birds were a very cooperative yellow billed cuckoo and an elusive green heron. The cuckoo posed for us, the green heron zoomed away. Later the heron zoomed in and landed above us near a second green heron. Two!

In the Nine Mile Run valley I marveled at this confluence of a muddy tributary with the main stem of Nine Mile Run. This, in microcosm, is like the confluence of the clear-running Allegheny with the muddy Monongahela River at The Point.

Our eBird checklist is here and shown below.
