Wing Flapping Displays As Agonistic Behavior

I introduced this series of posts addressing “agonistic behavior” with the following definition, from the Wikipedia article on the subject: “The term has broader meaning than aggressive behaviour because it includes threats, displays, retreats, placation, and conciliation.” This post highlights wing flapping by ducks as an example of agonistic behavior that is clearly not fighting (but could … More Wing Flapping Displays As Agonistic Behavior

The Agoni(stic) And the Ecstacy (Or Not): Bird Vs. Mammal

Juncos are fairly tough birds. They hiss and click if you unwittingly get near their nests. So if they can challenge humans, ground squirrels may well appear to them to be relatively easy to chase off. That is the way it seemed a month ago when two juncos challenged a rock squirrel in our front … More The Agoni(stic) And the Ecstacy (Or Not): Bird Vs. Mammal

I … More Motion Blur #2: Photographing American Avocets in Flight

A summer of learning: Butterfly upperwings and underwings

My first “wow” butterfly moment in the summer of 2015, described in Butterflies Part I, was really about butterflies and moths, and their antennae. The second moment of amazement is this realization: One butterfly, and in fact each individual wing of that one butterfly, can be very different when seen from above or below. Their … More A summer of learning: Butterfly upperwings and underwings

A summer of learning: How to tell butterflies from moths

It has been a summer of wonder and amazement, based on apparently chance encounters of this insect or that. But of course what we see— if we are watching—reflects what is here for now, in this season (or sub-sub-season). And so, it seems that one week, quite suddenly, our Cheshire neighborhood (Flagstaff, AZ) was home … More A summer of learning: How to tell butterflies from moths
