That Goldfinch seed is almost certainly not native Texas "thistle"

Is it really “thistle”?

Be aware of what Goldfinches like to eat. The small, black seed that Goldfinches are crazy about is not the same as the “thistle” that grows here in Texas. The popular seed for Goldfinches is Nyjer (nī-jĕr), which is only sold in bags because it comes from overseas. It’s a trademarked name. The U.S.D.A. requires that it be heated (250 degrees for 15 minutes) at customs. So its “freshness” has a life of only 6 or 7 months. Even with all this government-mandated processing, Goldfinches love it, and eat all of it instead of throwing it on the ground.   But they won’t if given last season’s dried-out Nyjer seed.

 Nyjer thistle is costly, so I mostly use ordinary Black-oil Sunflower seeds to attract Goldfinches, which is a far less costly seed, and they seem to eat it just as readily.

The very simple key to attracting birds to your yard

 

Whenever I talk with other amateur birdwatchers, one question that almost always gets asked is “how do I get birds to come to my yard?”.  The key is fresh seed!! You can have an expensive, gigantic birdfeeder located in your yard’s birdiest place. But if it’s filled with stale, un-nutritious birdseed, birds will look elsewhere in a hurry.

 

The seed you offer birds must be unquestionably fresh. For them, it’s a matter of life and death. Birds absolutely have to get top nutrition from all the food they eat. Theeey d9in’t caremif it cost you a fdew cents less. All they cvare abour is gettinjmg ther nutrition to make it through bad weather, or be able to attract a mate, or fly well enough to escape a predator, or fight off disease (take your pick - they could all end the same way).

 

To humans, birdseed all looks the same; but a wild bird can tell instantly if it’s been sitting in a warehouse or on a store shelf too long.  When seed is harvested, it has 100% of the naturally nutritious oil content. The longer it sits idly on a shelf, drying out, the less natural oil content it has - and the less attractive it is to a bird.

 

A bird has the ability to tell if a seed he holds in his beak is worth eating or not. He can tell in a micro-second, and may just throw it on the ground and look for a more nutritious seed.  They’re not being fussy, they’re just being practical. Some seed packages contain a lot of cheap filler. Or seed that our Texas birds don’t eat, like corn. Some packages contain a lot of non-seed junk; plant stalks, empty hulls, twigs, weed stems etc. You pay for this stuff, but wild birds won’t touch it.

The main purpose of the male Red-winged Blackbird's red "epaulets"

 

 

Red-winged Blackbird (male)

This time of year Red-winged Blackbirds are throughout north Texas. The Females are a non-descript gray and black. The male has reddish patches (about the size of a quarter) on each wing. These are used to claim and defend a territory. When the red “epaulets” were colored black in an experiment by researchers, the male usually lost its territory.

 They often hang out and hunt in large flocks, which may have some Crows, Grackles and Cowbirds in it.

A fable from another era about mothballs    Loose mothballs often get eaten by wild birds (which have no sense of smell) with very unhealthy results. I recommend a cluster of 6 or 8 mothballs however, bundled up in something like an old sock, to repel certain wild animals and loose dogs (which is a subject in itself). It’s NO LONGER a responsible recommendation to scatter mothballs on the ground. This is no longer suggested by researchers, or any knowledgeable or environmentally-aware person.

The canary just might be taking over the coal mine

 

Yellow-throated Warbler

Our wildlife, particularly birds, appears to be taking a big hit, while we take our time talking about whether global warming is real or not. Natural food supplies, breeding schedules, vegetative cover, prevailing winds, temperatures et. al. are all messed up.  For example, in  recent years, American Goldfinches started arriving in north Texas at the beginning of November. Last year it was about mid-November. This year, about early December. This sortr of thing may seem like a small matter, but there are hundreds of such examples. A few other proven, researched examples:

1.    In Arizona, the breeding season of the Mexican Jay has been pushed up 10 days between 1971 and 1998. This correlates with spring temperatures, which have risen 4.5° F in the same period.

2.    Robins in Colorado have migrated to higher elevations, where they breed two weeks earlier than in the late ‘70s. Many birds now arrive before the snow melts and uncovers their food. So they starve.

3.    The population of Edith’s Checkerspot butterfly, normally throughout the west coast, is drastically shrinking. In the southern part of its range, 80% of them are gone due to climate change.

4.    On Alaska’s Cooper Islands, populations of Black Guillemot’s are declining as the sea ice melts and recedes, affecting the birds’ primary food source, cod, which live under the ice.

5.    Red-winged Blackbirds now arrive at their spring breeding grounds in Michigan 21 days earlier than they did in 1960.

6.    Prothonotary Warblers have been arriving at their breeding grounds in Virginia one day earlier each year, for the last two decades, as spring temperatures have risen.

Do woodpeckers live everywhere?

Northern Flicker

Downy Woodpecker

Red-bellied Woodpecker

There are 215 species of Woodpeckers and closely-related birds worldwide. In north Texas, five species are fairly common: Downy, Hairy, Red-bellied, Sapsucker and Flicker. However, I can think of several others that make rare, accidental appearances here. The only lands that have no Woodpeckers are islands; Ireland, Australia, New Zealand, Sri Lanka and Madagascar.

 

High mortality right now.   Sadly, wild birds have a high death rate in cool weather – it varies among species, but can be as high as 70% of the first-year birds. This is mainly from exposure to the winds and weather, coupled with a lack of fresh, energy-producing food.

They seek out warm “roosts” for the night.   North Texans have been doing a good job of providing birds’ fall and winter needs, so we continue to have more birds here in cool weather, than in the spring and summer. Actually a majority of birds in north Texas don‘t migrate – they stay right here. Our winters are comparatively mild and, if birds can adapt, they’ll stay put. Cardinals, Blue jays, Chickadees, Robins, most Woodpeckers and Titmice are among those that stay in-state.

They may be less active (meaning they need less food and you see them less) but they’re HERE.  Some of the year-‘round birds are what’s called “partial migrators”. All that means is that they re-locate slightly (maybe a hundred miles or so, or into a valley) due to the available food.

How many birds was that?

You certainly don’t see every single bird that visits your yard, so how do you get a rough headcount? Or how do you authoritatively tell a friend there were xxx birds in your yard? Experts disagree on details, but they’re in the same ballpark.

Count the birds you see in your yard in a typical ten second span (count those at your feeders, flying nearby and those just watching). Multiply that number by 5 or 6 (that’s where they disagree) for a very approximate number of birds who look to your yard for support.

cold facts about shivering        Birds shiver in cold weather, just like we do.  Every bird in the world does it to keep warm. Shivering keeps the core body temperature where it needs to be (106-109 degrees for birds). That could mean a difference of 100 degrees from the outside temp to the inside of a bird.

There are reindeer in North America, but we call them "caribou"

The genetic makeup of reindeer and caribou is the same. The two main populations are in sub-arctic regions of Scandinavia and North America; these two populations have been separated for centuries,  and couldn't  interbreed. As a result, the two populations have evolved a little differently - the caribou being slightly larger than the Scandinavian reindeer

One member of the species has a glowing. red nose but scientists haven't located it yet.
