Dec 16, 2017: Mute Swans

I was surprised to find 2 adult Mute Swans among the 93 Trumpeter Swans this morning.  The sighting of this species was only my second for the Park.  There is no way of knowing if these Mute Swans are escapees or wild birds.  On the mornings of the 13th and 14th, 102 Trumpeter Swans were tallied.  The photograph shows 1 of the Mute Swans among 5 Trumpeter Swans.  Note the orange bill and black knob on the Mute.
