The sound of geese chatting and flapping their wings dominates the pre-dawn hour on the state park trail. Such vocalization and display on Jan. 15, can only mean one thing: the climate crisis has come home to roost.

There is the science of weather. La Niña is present but fading into a neutral state of the El Niño-Southern Oscillation. In other words, the weather is not doing much except what can be seen: ice melting, warmer ambient temperature pushing into the 50s, and lack of precipitation. So what’s up with these birds?

I know geese have strong bonds within mating pairs. They are particularly protective of their goslings. What I’m seeing now is not mating behavior, per se. It is a reaction to climate change in the form of over-wintering, early pairing displays, and vocal/aggressive behaviors. These behaviors are now normal near the lake where I take my daily walk, and in other parts of North America. The environment changed faster than their instincts evolved. What I observed in an earlier post is mostly pair-bond reinforcement and territory signaling, not actual breeding yet. I don’t need to be worrying about freezing little goslings in 3-4 weeks just yet.

Like with anything, my fellow early morning trail walkers noticed the noise and wondered what it was. I opined about it before really understanding the behavior. Geese will eventually adapt to changing climate. One might say they already are.
