This Douglas-fir tree laden with cones was a frenzy of activity yesterday. Black-capped chickadees, chestnut-backed chickadees, pine siskins and red-breasted nuthatches were busily harvesting the seeds in the warmth of the late afternoon sun. The chickadees and nuthatches seemed more interested in stashing the seeds, while the pine siskins were eating them.
It is interesting to note how long the seeds stay in the cones once they are mature. It seems like the tree is holding onto to them as a food resource for animals for the winter. Likewise, as the birds were foraging, many of the seeds were dislodged and were whirling through the air to the ground. It’s as if the birds were sowing seeds for future generations. The woody cones are well designed to protect the seeds from the weather. I investigated some seeds that fell to the ground, and they were in excellent condition.
