The Bog BioBlitzers!


Scanning for Upland Sandpipers (no luck!) but the field did hold a pair of Sandhill Cranes.


Sedge Wrens were still singing.


A real treat! Watching 3 Boreal Chickadees along Arkola/CR52 near Owl Avenue.

This young Black-billed Magpie was seen by the birding group


This Goldenrod Crab Spider (Misumena vatia) has taken on the yellow color of the Brown-eyed Susan to better camouflage itself from potential prey.


Twelve-spotted Skimmers are always a treat to see.


Wood Nymphs were on the wing in the afternoon.


Dun Skippers were quite numerous.


It was great to see some young folks and families attend the event. Today’s kids are the Bog‘s future.

A severe windstorm the night before the event took our beautiful big White Pine that anchored the parking lot and many winter bird feeders. It will be sorely missed!


By the looks of the trunk, the tree was well rotted and not long for this world anyway.


Dr. Tim Craig from the University of Minnesota Duluth brought his great enthusiasm for insects and galls with him to the event, and shared it with many.

Leaders and participants swap stories from the day in the field. Jerry McCormack (standing left) was our butterfly leader.


Northern Water Plantain (Alisma triviale) found at Nichols Lake.

A real treat for the bird group during the Bog BioBlitz was the close appearance of a beautifully marked juvenile LeConte’s Sparrow on Dart Road. This awesome photo is by Casey Weissburg, on of the participants.

Earthworm leader Jinny Alexander turned up 5 species of earthworms on this day…A good thing? Probably not, as all earthworms in Minnesota are “non-native” and often damage woodlands. Fortunatley bogs do not have much mineral soil and so worms are scarce there. [photo by Rubin Stenseng]
