Great Backyard Bird Count 2011

Did any of you take part in the Great Backyard Bird Count this year? What did you see?

My son counted:
Mourning Dove – 8
Inca Dove – 1
Anna’s Hummingbird – 2
Black Phoebe – 1

What was a very noticeable change from his count last year was a lack of house sparrows and house finches. It could have been the time of the day he counted, and the fact it was cold and rainy.

We weren’t worried about house sparrows, because we still see them all the time. Here’s one from the park the other day:

But we had already noticed fewer house finches in our yard, even though we were feeding the same kinds of seeds in the same kind of feeder. Checking the previous count totals for our city in previous years we see 138 house finches were counted in 2009, 102 in 2010 and now only 31 so far this year. House finches are native to the Southwest, so we checked to see if the trend carried throughout the state. Sure enough 7,978 house finches were counted in 2009, 7,132 in 2010 and only 3,821 in 2011 (not all reports made yet).

The Black Phoebe is an interesting new addition, although I noticed this morning that the male Anna’s hummingbirds are giving it trouble so I don’t know whether it will stay.

What birds did you count this year? Do you have house finches?

Did you search through the counts from previous years?

Bug of the Week: Aphids

Aphids are actually cool insects.

Look at the way the light passes through their antennae and the “tailpipes” on their back ends, which are technically called cornicles.

But most aphids are cool insects in another way, too. They like cool weather. As soon as it gets relatively warm here in Arizona, they are gone.

In fact that one with wings, called an alate, is probably getting ready to go. Can you see the “tube” it uses to suck juices from the flower bud? That’s called a proboscis.

When aphids arrive where you live, see what you can discover from looking at them closely. Let us know what you find out.

Seed of the Week: Luffa

Our mystery seeds last week were from a plant that probably not many people grow.

These black seeds are from luffa sponges, genus Luffa.

The plants belong to the same family as squashes and cucumbers. The have large yellow flowers, a vining growth habit, and fruit that roughly resembles a zucchini or cucumber.

The young fruit may be eaten. For example, in Asia the young luffas are used in stir-fries (peeling off the bitter skin is recommended).

The seeds were on the ground near a bin.

I don’t think anyone would want to eat these, but they were for sale. Why?

If you peel off the brown outsides, you will discover why.

There’s a beautiful luffa sponge inside.

We bought some seeds of two different kinds, so hopefully I’ll be able to show you more about growing luffas next fall.

Have you even grown or used luffa sponges?
