Nesting Red Crossbills-DeWeese Res Custer Cnty

[Gregg Goodrich]

Today 3/17 we had a pair of nesting Red Crossbills (Ponderosa Pine Type 2) building a nest and eating the cones on the Ponderosa pines at DeWeese Reservoir in Custer County. Is this early or normal? Photos, recording and more details on list.

Greg and COBirders--  Nice find!  The Colorado Breeding Bird Atlas II lists the Red Crossbill’s breeding season as beginning around March 15 and continuing into October.  Arkansas Valley Audubon’s newly revised Wet Mountain Valley checklist shows this species as “uncommon” the year around.

Thanks for all the good responses. Looks like this is the beginning of the normal time for breeding but can occur anytime of the year if the cone crop is good.

Thanks

Red crossbills have recorded nesting in all 12 months in CO (Bailey and Niedrach).
