Savannah Sparrow Fledged

Savannah Sparrow Fledged - Passerculus sandwichensis

Early in the spring I usually see a Savannah Sparrow sitting on the fence around the Glenmore Runoff Reservoir. Since late June I have seen newly fledged Savannah Sparrows in the same area. 
Savannah Sparrows nest on the ground. There is a grassy hill that leads up from the walking path to the fence around the reservoir. I commonly see the Savannah Sparrows fly to or from the fence from this grassy hill, and I presume this is were the nest is located. 

There are usually 4 to 5 eggs, incubation is for 8 to 12 days, and the young are fledged at 8 to 14 days of age. Savannah Sparrows are double and even triple brooded and the bird in the photo above taken on July 16th was from the first brood.
