Hi, this is a strange one. I have a shrub app 2mtrs from our fishpond, I think it's a Black Phoebe, strange name as it has white spongy puff balls. Over the past few nights a dozen or so of these puff balls have appeared right next to the pond edge & appear to have been broken up. None are actually in the pond. The first time we saw this I swept them away, but they were back the following morning? What on earth is going on. The only wildlife we have around are Squirrel, Magpie & Rooks plus the usual array of birds oh! & the odd cat taking a short cut. All the pods taken from the plant are deposited next to the pond, none are on the ground around the plant. This is weird. Any thoughts are appreciated.
