Species, Date, Time and Location Information
Little Blue Heron
Duration (total time in view):
Sun was slightly to the S - SW and the bird was seen in the NE corner of Lake Sheridan.
Description of the Bird
On April 24th approximately at 11:30am I was leading a group of birders to Wray, Colorado. We stopped at Sheridan Lakes, CO to see what birds are to found on the lake.
The day was overcast and windy and temps around 50 degrees. As we drove down to the lake a group of 2 Great Blue Herons (Ardea herodias) were flushed along the lake shore along with a lone Little Blue Heron (Egretta caerulea).
The Little Blue Heron was in full breeding plumage.
Size: Roughly half the size of a Great Blue Heron
Bill: Smaller in length and width of a Great Blue Heron. Bi-colored bill - the inner half of the bill showed a pale blue color and the outer half being a darkish black color.
Upper parts: Smoky purplish blue color on most of the body except the neck was a lighter violet color that was seen in good light as the heron flew over us and then banked south over the lake.
Legs: were smaller in length compared to the Great Blue Heron and had a greenish color tone to them.
In flight the legs trailed behind the tail as most egrets / herons do in flight.
Time of observation: 4-5 minutes.
Experience: Seen many Little Blue Herons in Texas and Florida. Seen 3-4 Little Blue Herons in Minnesota.
Behaviors: Heron was most likely searching for food along the lake until my group flushed the bird as we approached the lake with our vehicles.
Call: None was given
Plumage: Breeding adult
Similar Species Discussion
I eliminated Green Heron by size and also Green Herons have a reddish neck and dark bill.
Tricolored Heron: Lower white belly and upper dark breast, even though they both of bi-colored bills the neck pattern was eliminated right away.
Reddish Egret: bi-colored bill had the wrong color with reddish egret having a fleshy pink base and dark tip. Also the reddish neck and feathering was eliminated from Little Blue Heron
Seen many Little Blue Herons in Texas and Florida where I once lived in these states. I seen Little Blue Heron almost every day in these states. I also seen this casual species in Minnesota.
