Downy woodpeckers are native to the (mainly deciduous) forested areas of North America. They are the smallest of the woodpeckers in N. America —14 to 18 cm (5.5 to 7.1 in) in length. They mainly eat insects, but they also feed on seeds and berries. They are a natural predator of the European corn borer, a moth that costs the US agriculture industry more than $1 billion annually in crop losses and population control.
I had fun painting this one with Ian de Hoog as my instructor.
I always love a Jean Mackay class. Here in SoCal we don’t have many deciduous trees, so it’s not likely I’ll get to see a lot of abandoned nests in bare branches in the coming months. But I’ll be keeping my eyes open, just in case.
I am not sure how I got to be middle-aged before learning that butterfly caterpillars don’t spin cocoons. Moths do that. A butterfly’s chrysalis forms INSIDE its caterpillar-y skin. It sheds that skin and voila, it’s now a pupa. 🤯 Learn something new!!
Willow ptarmigans (Lagopus lagopus) in the Arctic change colour throughout the year, from completely brown in mid-summer to completely white in mid-winter. The transition (which starts from the head and moves down) is triggered by changing day length, not by temperature.
With a warming Arctic, we are now seeing snow-white birds in a snow-less landscape. Where once they were perfectly camouflaged as the seasons changed, now they are sitting ‘ducks’ for predators. The climate change is happening too quickly for them to evolve to meet the new conditions.
The willow ptarmigan’s scientific name, Lagopus lagopus is derived from Ancient Greek lagos (λαγως) ‘hare’ + pous (πους) ‘foot’, in reference to the bird’s feathered feet which allow it to negotiate frozen ground.
Thanks, Max Romey, for introducing me to this bird and its story.
Shadows can reveal things we may not otherwise notice. We might see new details or shapes, or even additional organisms that were not at first obvious. Shadows also highlight the shape of the object on which the shadow is cast, and show which parts of the organism are touching the surface. They can help explain complex shapes and how parts fit together.
Thanks to natural science author and illustrator Robin Lee Carlson, I now understand why a water strider’s shadow looks like it has big round feet. Fascinating.
