House Finches: Nesting and Chicks!

 

One of the most common sounds of the spring are the high, melodic warbles of the house finch. House finches are becoming increasingly common, and are in fact an invasive species that are beginning to replace the purple finch.

 House finches were first introduced as pets for the males' bright crimson heads and sweet songs. Pet stores imported these birds from their native habitat of California. However, once this illegal behavior was discovered, shop owners did not hesitate to release these birds into the wild. In the wild, they out-competed purple finches for food and habitat until they became a common sight in nearly every state. How can you tell which bird is which?

The purple finch's bill is conical shaped, whereas the house finch's bill is curved slightly downwards. However, this is very hard to observe from a distance, or even from reasonably close.  The male purple finches have less streaking than the male house finches. While it may take some practice to discern between the two, identifying them should become easier after you see both kinds.

House finches are especially common because they thrive near humans, and often nest in door wreaths! During the mating season, males present females with gifts of regurgitated food and nesting materials. The female, however, actually builds the nest. The pair remains together, with the male defending the female. Unlike most birds who defend the nesting territory, male house finches defend the females themselves.

Once the nest is built, the female lays her eggs. She lays 2 to 6 light blue speckled eggs, and incubates for 12 to 14 days. Once the chicks hatch, the mother feeds them regurgitated seeds until they leave after 11 to 19 days. The males help with this task by feeding the females while on her nest. Even after the young leave the nest, the parents continue to feed them until they find their own mates,

 

I saw these house finch chicks in my neighbor's door wreath!

 

Only two days later and wing feathers are almost developed!

 

 

Miniature Tutorial: Sushi!

 

With this tutorial, you can learn how to make an avocado 'caterpillar' sushi roll!

1. Roll out a rectangle of black polymer clay: 

 

2. Trim it into shape with a polymer clay razor or Xacto knife.

 

3. Roll out a thick log of transparent clay. Transparent clay looks like and off-white color. I also found that mine glows in the dark!

White clay is on top, transparent is on the bottom

4. Flatten the white clay and wrap it around the transparent log. This is the beginning of your rice.

 

5. It should look like this:

 

6. Roll it out until it is extremely thin. You should have a substantial length. Make sure your clays are warm because if they are too rigid your string of clay will break when you roll it thinly!

 

7. Position it on the black rectangle, cutting it to length and repeating until it covers the rectangle:

 

You should see a transparent circle surrounded by a white coating.

8. Make your fillings! You can experiment here, but I made a shrimp tempura and vegetable filling. First, roll out 3 thin strings of orange clay and 2 thin strings of white. I did not have orange so I mixed yellow and a speck of red.

 

9. Stack them! 

 

10. Roll them!

 

11. Make two similar strands of green. Stack all of them next to each other and place them on the sushi, black rectangle (seaweed) side up:

 

12. Roll up the sushi! Pick up one end of the rectangle and bring it over the filling.

 

13. You will have some gaps in your seaweed. Fill them in with more 

'rice.'

14. Now, cut your sushi! 

 

 

15. Make the avocado using the images below:

 

Add some more streaks of yellow, dark green, and light green than shown here.

Crumple it into a ball

Flatten it and add some more streaks. Make sure your clay is warm (by kneading it in your hands), otherwise it will break!

 Cut it into small strips, and place them on top of your sushi:

I made these sushi rolls as a polymer clay cane, and attached them to cut strips of balsa wood (found at a craft store). A tutorial is on its way!

Patriotic Pigeons

        

             When you stroll down a city sidewalk and see a pigeon poking at a pizza crust, it might not occur to you that the feathered scavenger with a goofy walk may be descended from a war hero. However, pigeons have been used in wars to transmit messages ever since the ancient Romans. Although the carrier pigeon system may seem unreliable, one homing pigeon saved nearly 200 soldiers in World War I. In addition to being used for transmitting messages, pigeons were trained to command missiles in World War II by pecking at a target for food. Although they performed impeccably, the military decided the project was too time-consuming and challenging to pursue.

    At the decline of World War I in 1918, during the battle of Argonne in France, 500 Allied soldiers were trapped. Protected only by a several-foot heap of soaking mud, German shells and bullets whizzed over their heads and zipped through the soggy clay. Their only food supply consisted of a few crusts of bread carpeted in dark grey, bristling mold. Days dragged on, yet no Allies knew of the starving soldiers. Charles Whittlesey, the leader of the trapped Allied division, had no means of communicating their location except for three carrier pigeons. The remaining soldiers gazed up in hope as one pigeon, with a message attached to its leg, soared upwards. However, no sooner had the pigeon left the trench when Germans spotted it and sent it crashing to the ground in a flurry of bullets. After the death of the second pigeon, the remaining 194 soldiers’ only chance to live depended on one pigeon, Cher Ami. She flew several miles, surrounded in storms of bullets. One tore through her leg and another ripped through her chest. Her strength faded and gave way to pain as she spiraled down to the ground. Then, she managed to draw a last ounce of strength, fight against the whizzing shells, and soar above the enemy fire. With her leg dangling by a tendon and a gap in her chest, Cher Ami still managed to deliver the message. This message saved the lives of all 194 soldiers, and Cher Ami became a war hero. Medics scrambled to save her life, but could not save her leg. Cher Ami was sent to the U.S, and died six months later from her injuries. The story of Cher Ami shows that even animals regarded as common and insignificant can have a great impact on the world.

    

    Although pigeons have been used in warfare for centuries, behavior psychologist Frederic Skinner devised a new, revolutionary use of pigeons in World War II. When the Germans bombed Poland in 1939, Skinner wondered if missiles and shells could be guided to a target from an aircraft. He found his answer not in extensive research, but in his own back yard. As he watched a flock of birds settle to the ground, and then lift off in a moving carpet, Skinner “saw them as `devices’ with excellent vision and extraordinary maneuverability,” and wondered if they could be trained to guide a missile. He decided to use birds because of their superior eyesight to humans, agile movements, and ability to remain comfortable in the air. Skinner then chose to focus on pigeons for their predictability. He taught the pigeons to peck at a target image to earn pieces of grain. Once the pigeons were conditioned to peck the target, Skinner built a steering system of lightweight rods strapped to the pigeon’s neck. When it lunged to tap the target image, the rods closed an electrical contact, moving the missile. When the target moved off-center, the pigeon would poke vehemently at it, steering the missile back on its course. Convinced that his idea could help end the war with fewer deaths, Skinner submitted his project to the National Inventors Council, but was met with refusal. Undeterred, he sent a proposal to Office of Scientific Research and Development, and, this time, was accepted. Before being implemented, Skinner tested the pigeon-guided missiles under conditions simulating those in battle. Pistols were fired, barely grazing the birds’ heads, yet their eyes remained fixed on the target and they barely even shifted a toe. They were also subjected to blinding, white flashes simulating shell bursts, but their minds remained intent on receiving a kernel of grain. Even when Skinner placed a pigeon of the opposite gender beside the missile commander, the pigeon’s hunger overcame all desires, and it hammered away at the target without stealing a glance. “There could scarcely have been a better demonstration of the extraordinary predictability of behavior, the keenness of a pigeon’s vision, the accuracy of its responses, and its freedom from distraction.” Despite the promising prospects of Project Pigeon, it was canceled, thought to “seriously delay others...which have more immediate promise.”

    The results of the Project Pigeon experiments indicate that Project Pigeon may have been a tremendous success. Perhaps World War II may have ended sooner with far fewer deaths if Project Pigeon was implemented. Even animals such as pigeons that we often take for granted, or even consider a nuisance, could have a drastic impact on the world. Cher Ami alone saved 194 lives, and, if pigeons were used to command missiles, they could have saved hundreds more.
