I observed the Red-necked Grebe pair at Lake John Wednesday afternoon, late Thursday afternoon and Thursday evening, and again this morning. The birds continue to incubate. On Thursday, 3 eggs were visible in the nest, though there could have been more hidden by the vegetation of the nest.
The pair, particularly the male, are agonistic toward other species approaching the vicinity of the nest. Assuming viable eggs, a hatching could occur at any time. Observations during the weekend or next week could be rewarded with glimpses of young. There are three young Pied-billed Grebes near the Red-necked Grebe territory, and they could be confused with young Red-neckeds since the face patterns are similar. The grebes appear to be tolerant of a vehicle parked at the entrance to the pullout near the nest being used as a blind. However, emerging from the vehicle appears to generate alertness from the grebes and may alter behavior. A CPW volunteer monitors the area for potential intrusions such as loose dogs, and he tells me these have been minimal. These birds are a joy to watch. -- Chuck Hundertmark 2546 Lake Meadow Drive Lafayette, CO 80026 303-604-0531 Cell: 720-771-8659 [email protected] -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
