wow... you spotted them, too :D they represent two more SBI shares btw ;)

It's really crazy what the GCam App can do! It's Google's exclusive camera App for their Pixel phones but you can get inofficial apk's of modded versions that work well on a whole bunch of other android phones.

I have no idea what they are, though, and I didn't even see them at all with my own eyes... I'd have to speculate they are some "common moorhens" as those populate the pond a lot. They look too small on the photo to be ducks I think!
