The Ferruginous Duck on Middle Marsh has a ring and let's face it the likelihood of another Ferruginous choosing that lake as a nice place to hang out, was statistically impossible so it must be our original bird returning.
But one can't help wondering where it went and if only we could get the ring number, that would reveal a thing or two.
It makes me grumpy hearing people making the assumption that a ring means escaped, it proves nothing.
So today was work party and just minutes before more wildfowl went over, with at least 4 being Pintail. Jack told me during the work party another flock went over earlier.
