I saw six crows overhead on a warm winter’s day. Flying not so much in formation but instead in a proximity of convenience. Was this some communal group? A family? Or even six adults, three couples? They were high enough above I could not see detail, but the setting sun cast rose gold light, turning their black bodies brown and gold in the fading day.
What did they think of this unusually balmy December day? This long string of especially warm days? Is there a difference between a dry, dormant winter in the desert and a cold bitter winter in terms of food supply?
Is there more opportunity?
Or, while we’re speculating, does the opportunity come in waves? Extra food now means less food later. Insects emerge early looking for winter ephemerals (i.e. dandelions), but all they find is a hungry maw willing to sit with murder.
So the crow gets extra food, but, whatever this generic pollinator might be (whether beetle, or grub, or butterfly and moth), it’s still getting eaten early, disrupting its chance to propagate its species. Instead of one beetle, given a chance to reproduce, do we have two beetles, or fifteen? Or fifty?
The problem is we’re speaking in generalizations, speaking as if one crow and one beetle represent all birds and all insects. It also needs to be cleared up that all this speculation is not entirely in line with observations made in the garden.
If we are speaking of just one beetle, we can speak of the pine beetle, which threatens the native ponderosa pine.
The danger of all this speculation is that we might start connecting dots when there really is none. Do crows eat pine beetles? In a way that might significantly help control the infestations affecting our forests?
Yes. No. Maybe? Like I said the field observations don’t support this propped up, amateur hypothesizing but maybe that just means I need to spend more time in the field.
Crows eat insects. Pine beetles are insects. Crows eat pine beetles? Well, sure I’d guess they might if they can get to them but when you think of their respective ecological niches how much do they overlap?
Maybe a lot but I don’t know if I’ve ever seen crows perched vertically on a trunk like a woodpecker, so maybe they have a different way to get the pine beetle under the bark.
So maybe they would if they could with the beetles. I am going to do some research and will post more about this when I have answers. But for now, back to speculating.
It’s this record warm weather that is creating so much disruption. So much opportunity for the opportunistic.
Do crows see it as such? See it as an opportunity with no larger frame of reference? An opportunistic species taking advantage of unseasonably warm weather, making hay while the sun shines.
Mild and nice, while west in California they’re dealing with atmospheric rivers. It’s like the planet wants to park long-term the dry 65 degree weather in one spot and the torrential deluges in another. Yes, that’s plural of deluge. The water just keeps on coming even after the ground is saturated. That’s when things would get really dangerous except here in Colorado the garden it’s dry.
We could use some of that rain, and California could use a little less.
