One Down; Three To Go
Curlier in large.
I went looking for the robinlings, but they've got more sly. I could hear them peeping, but they squeak in pure tones like crickets so seem almost impossible to locate effectively by sound. I spotted one deep in a flowerbed, but they've also got more skittish (phew), and it disappeared almost as soon as spotted it.
I did get a clear view of the father singing his heart out though.
AND, it turns out the tendrils also suffer that curly phone cord problem.
p.s. Bonus bumblebee
