A female goosander was on the river also dipper nest building also:
song thrush singing
turkey tail fungus
this is what i believe to be material from a predated frog or toad which leaves a crystal jelly like substance behind which is called star jelly
A quote from chris packham
Latest tests done at the Natural history Museum show that after extracting DNA they found it to be from the common frog, it is a Glycoprotein stored by the female used to coat eggs, it is extremely good at absorbing water even from surrounding air, they strange bit is that they found other DNA within it and after running this through there sequencer they found it was from Magpies, although other avian frog predators could also be responsible, apparently it is released during the killing of the frog and not regurgitated or passed from eating them..
