Squeals in the sky and a pair of unseasonable visitors on the ground, and more ...


red-tailed hawks
High-pitched squealing cries in the sky ... I had been sitting in the porch reading but jumped up and ran outside: high up in the sky two hawks were slowly circling, so high that they just looked like two winged spots. I had heard these squeals before coming from a red-tailed hawk nest in the neighborhood. My camera with telephoto lens brought the birds a bit nearer: a wind-blown parent and a compact neat-looking youngster that was vocalizing for the entire time that I observed it. Maybe it was on its first high-altitude flight and needed reassurance from its parent :-)

Yesterday afternoon I was working on the porch and casually looking up was thrilled to see two evening grosbeaks on the ground below the feeder; the first ones for me, and out of season too since they are usually only seen in the winter. Dave Johnston, who I ran into by the boat house near the Marina, told me who saw a group of EG on the West River trail at its Black Mountain Rd end. Maybe it's an early sign of fall?

The two Evening Grosbeaks took off when my dog decided to investigate what I was looking at. Soon however another visitor settled in the grass looking for seeds, a very handsome male lst-winter Rose-breasted Grosbeak.

Later on, the tree, and the grass skirt around it, were overrun with Goldfinches, all males who were making quite ruckus. Actually I have never seen goldfinches forage on the ground for fallen seeds even when the feeder was empty.

Here are follow-up photos of the molting Blue Jay, who looks like his head feathers are starting to come back in,

and Northern Cardinal, who is still losing his,

and a new baldy, this very sorry looking Red-Bellied Woodpecker who just grabbed chunk of suet from the feeder.

It's getting dark and starting to drizzle, but the Goldfinches are still at it.

Electronic Birding Guides

I am planning to go on a pelagic trip toward the end of August and was considering what fieldguide to take along, preferably one that didn't weigh much. For the past couple of years I'd been using the ufg guide (formerly "Peck") from Eduneer.com on my Palm TX and had been fairly happy with it, but it lacked photos of the seabirds I was expecting to see. Also the screen of the Palm is almost impossible to see in sunlight. I investigated other platforms and decided on the IPod Touch which looked beautiful on photos. I bought it at Amazon and downloaded National Geographic's Handheld Birds and iBird Explorer Pro for $14.99 and $29.99 respectively. Both performed nicely outside in partial sunlight, but I much prefer the iBird Explorer Pro which has a wealth of information, i.e.both drawings AND photographs, text, maps, audio etc, much more than the National Geographic program. Here are some photos of the critical test, how does the IPod Touch compare to the Palm under these condititons?

The first photo is a juxtaposition of photos, in partial sunlight, of a Orchard Oriole on the IPod Touch using the iExplorer Pro program, and on the Palm using the ufg guide.

This photo compares drawings on National Geographic Handheld Birds, which has no photos, on the IPod Touch with the same photo as above on the ufg guide.



The last photo is taken inside, eliminating the sunlight as a confounding factor.

When held in direct sunlight the picture on the IPod Touch is recognizable whereas on the Palm it is not. Of the three birding programs the iBird Explorer Pro gets my vote. As to seabirds, it does great job too with both drawings and photos, range maps, facts, and Wikipedia which requires a wifi connection.

Changing Feathers

Seasons are a-changing... birds are a-molting... Here is a Blue Jay that, I believe, is about to go bald and doesn't look too happy.

The colors of his back are still gorgeous despite the wear in the white feathers with their broken tips.



This male Northern Cardinal is not far behind. He too is losing his crown feathers.

He is still feeding this youngster, or lurking in the back, as he does in this photo.



Lastly yesterday we had a flock of Tufted Titmouse fledglings in and out of our crabapple tree begging for food.

These fledglings are still cuddly in their juvenal plumage which will soon be changing. Flight feathers are already fully formed.
