Rain Birds

The back country is wet, which does not encourage one to go off trail. Twice in the past three days I have visited Sax-Zim Bog and the water next to the dirt roads is amazingly deep. The reason for my visits is we are now entering the time period when both Great Gray Owls and Barred Owls have their owlets hatch, which means both species often hunt well after sunrise. While I have not seen any Great Grays (bummer) I have found the same exact Barred Owl twice. At this point I do not know if it is a younger owl that did not mate this year, or whether a nest is in the vicinity. Regardless here are a few pics from Sunday morning when the yellow globe came out briefly.

I also watched this Chestnut-Sided Warbler (and a whole bunch others) near my home


Here is a timeline for Great Gray Owls which I put together. It assumes a nesting date of May 1st (adjust earlier or later based upon your own sightings). Shortly after hatching the views of Poppa GGO with the need to hunt increase.

Nesting Date: May 1

  • Incubation Time: 30 days (End on June 1st)
  • Time in Nest: 28 days (End on June 28th)
  • Exploring on Ground or Snags near nest: 7 to 14 days (End on July 4th to 11th)
  • Flight (Start July 4th to 11th … mid July)
  • Independent by late Summer

Sax-Zim Bog Predators

My daughter’s plan was to visit us today … arriving up from the Twin Cities around 9:45 am. Thus, naturally I thought that meant there was time to go birding at Sax-Zim Bog before she arrived. I left home at 5:25 am, and the Bog did not disappoint. Predators like to nest or have their young early in the year to make their youngster’s huge appetites correspond to when other animals and birds have their young.

I found another Great Gray Owl hunting well past sunrise. I suspect it is now hunting for two adult owls … itself and its mate which is back on the nest. Thus, the two Great Grays I have found in dramatically different parts of Sax-Zim now gives me a good idea where of the vicinity of two owl nests.

With respect to Red Fox, their young were born some time ago, and the fox kits are starting to come out and play. Apparently foxes like the same forest region as one of the owls. The Red Fox and Great Gray were seen and photographed quite near one another! Wherever you live it is time to invest in searches which will pay dividends in 6 to 8 weeks. Days following stormy weather (like yesterday) are always a smart time to head into the outdoors. Predators are likely to be hungry after a forced day of fasting.

Great Gray Owl Hunting

It was  quite windy earlier this week, and when Tuesday morning was forecast to be calm and overcast … hopefully with no rain, I trekked over to Sax-Zim Bog. Not many returning migrants were yet around with the exception of Sandhill Cranes which I saw many places. One of my bigger surprises was finding a huge flock of evening grosbeaks … mixed sexes. I would have though these finches would have returned deeper into the Boreal Forest in preparation for the breeding season, but the grosbeaks were not in any hurry to end their winter patterns.

Later in the morning, I stumbled across a Great Gray Owl in an unusual location hunting long into the daylight hours. The owl even put up with small amounts of drizzle. I watched the Great Gray hunt for over 75 minutes with nary a car or other person present.

Here is my first view of the owl … however within 10 minutes it flew over to hunt only 20 yards from where I was standing!
