sandpiper

 A hot sultry day in August.  The pond was quiet.  Several rocks appeared offshore in the last few days, exposed by the lack of rain and lower water level.  Good for sandpipers hunting lunch.  This Solitary Sandpiper Tringa solitaria shows off its white eye ring while it waits on a rock to spot a meal in or on the water -- aquatic invertebrates such as larvae, worms, flies, or mollusks.  

dragonflies on branch

We love the branch over the pond, since it is a platform for all flying creatures to settle on for a short time.  Usually we get a close look at birds pausing there.  Now, in mid-summer, the dragonflies and damselflies use it too.

emerged

We have been watching the cocoon since it was re-attached to a willow stem two days ago.  Today the Polyphemus silk moth Antheraea polyphemus emerged.  This adult will live 3 or 4 days. She will not hunt or feed, only seek a mate in her short existence in this form. The life cycle will start again when she lays eggs; the eggs will hatch caterpillars that will eventually cocoon to become as handsome as this adult.  Look closely -- the 'eye spots' are as transparent in real life as they look!

first hatched

The post on 4/23/2014 was about a nest containing two eggs.  If you guessed it was a Northern Cardinal nest, you were correct.  Today the first egg hatched, after at least 14 days of incubation.  (Usually the eggs hatch after being kept warm and turned frequently by the female for 12 or 13 days, but we've had cool wet weather this Spring.)

In the photo at left, we see the hatchling's back side with sparse tufts of grayish down where more feathers will grow.  Other than these tufts, the baby bird is naked.

In the photo below, we see the front belly-side of this same baby bird. It already has the distinctive thick bill typical of Northern Cardinals. Note the amazing detail of its feet and claws!  Belly is transparent enough to show internal organs.  Eyes are not yet open, and it will be very clumsy for a few days but will flail around trying to reach food as a parent approaches.

eye shields

I've occasionally noticed something about the eyes on some of the birds I observe: milky or filtered texture.

According to the Cornell Lab of Ornithology http://www.allaboutbirds.org, birds have what is known as a nictitating membrane or “3rd eyelid”.

This membrane is a translucent or clear eyelid, closest to the eyeball. A bird will close these membranes over their eyes but can still see through them to protect their eyes when needed, such as in flight, while hunting, or to dive under water.

This Northern Flicker may have been trying to shield his eyes from flying bits of bark as he probed for insects.
