The colorful, melodious Dickcissel (pronounced "dik-sizzle") lives from central Texas all the way north through Minnesota and North Dakota. But not in Denton, although it used to be abundant here. Ten or fifteen years ago the birds were abundant in the Denton area. The epicenter seemed to be the Rayzor Ranch, at University & I-35, where thousands of them lived in the tall grass, amid the Longhorns. That's all gone now, and the only Dickcissels are a few found in fields on the outskirts of town.
They are late migrators, arriving (if at all) in late April from their winter homes in Central and northern South America. Here, during breeding season, they feed on both insects and seeds, and make nests amid tall prairie grasses (over a dozen grass species are suitable, bluestem and indiangrass among them).
If you control insects with ladybugs (and lots of us do) I recommend that you release them in your yard at dusk. Why? The domestic varieties want, instinctively, to return to their place of birth - often the foothills of the Rockies. They don't fly at night, so by releasing them at dusk, they'll stay around long enough to lay lots of eggs; and they won't get eaten by hungry birds.
Asian ladybugs began to be imported several years ago. They want to get in your house, and can be a nuisance. I recommend you not buy them! If the merchant where you shop doesn't know where they're from, shop elsewhere.
This past October 9th I ran a pucture of a brownish native plant asking "is this plant really dead?" It wasn't. It had gone into dormancy in August, due to our extreme heat. It's a Wafer Ash, and it greened up just fine about two weeks ago.
