Bird Bill of Fare

Have you ever tried to eat soup with a fork or salad with a spoon? People have learned to use the utensil that works best for different foods they are eating: soup—spoon, salad—fork, and even fries—fingers. Birds do the same thing, only instead of using utensils they use their beaks.  Birds have very different types of bills depending on what food they primarily eat.  There are beaks for snatching bugs, spearing fish, probing flowers, cracking seeds and tearing meat.  All of these beaks have evolved to fit the birds’ diets perfectly.

Seed eaters and bug eaters have similar beaks. They are strong enough to crack seed shells, and thin enough to capture bugs from tight spaces. The size of the beak varies greatly among these birds, ranging from the small, dainty beak on this Eastern Towhee to enormous toucan beaks used for feasting on fruit and insects.

A Full Day Indeed

group in Burrell Boom

Ten p.m. It’s dark, and the night sounds of crickets are competing with the repetitive whirr of the oscillating fan,s which are helping keep our rooms quite pleasant. We are exhausted, which is reasonable considering our travel began at 5 a.m., and with the time change in Belize, it is really midnight to our bodies. Yet our minds are racing with excitement over the marvels we have seen so far in Belize.

We’ve learned a little about the history of Belize. We stopped in the village of Burrell Boom and saw the “boom,” or chain, which held back the mahogany logs when they were being harvested and transported by river downstream before being loaded onto boats.

At the Community Baboon Sanctuary we had an introduction to many medicinal plants, including the plant which is supposed to help cure warts. Chris volunteered to be an experimental subject.

Did you say proboscis?

Moths, and butterflies, are both part of the Order Lepidoptera, being scaled, flying insects. Moths comprise roughly 90% of the known species of Lepidoptera, with multiple clades, superfamilies, and families of moths, while butterflies are only about 10% and all are contained within a single Superfamily the Papilionoidea. With some 160,000 moth species it’s no surprise that some moths are more closely related to butterflies than they are to other moths.

There are several commonly “known” ways to differentiate between moths and butterflies, however there are exceptions to every single method. Many butterflies are brown, such as owl butterflies, and many moths fly during the day, for example urania…

What Time is it in Nature: Woolly Pipevine

July 19, 2014

North Carolina has a variety of native flowering vine species that grow up trees in forested areas. One species, the Woolly Pipevine (Aristolochia tomentosa), is both interesting to look at and is an important food source for a popular insect.

Woolly Pipevine Plant

Woolly Pipevine is a tall, climbing, woody vine native to most of the eastern US. Though it needs support to gain much height, the vines can easily reach 30 feet tall if well supported by a tree (or a trellis in a landscaped environment) as it grows up the trunk. It has big, heart-shaped leaves that can reach 10 inches long and are deep green on top and paler green underneath. Both the common name, Woolly Pipevine, and the species name, tomentosa, refer to the surface of the leaves, stems, and flowers as they are covered in dense, short hairs.

The “pipevine” in the common name Woolly Pipevine comes from the interesting flower:

Woolly Pipevine Flower

The flowers resemble the pipes smoked by the Dutch and northern Germans in the past, with a sort of widened bowl sitting at the tip of a longer curved tube. The flowers bloom from May into June and reach lengths of just under two inches long, though you might not see the flowers in spite of their size as they tend to grow back behind the leaves and are subtly colored. They have an interesting form of pollination. When a fly or bee follows the sweet smell to the flower and crawls inside to gather nectar, they rub against the stamens that line the inner flower and are dusted with pollen. The tube of the flower is also lined with hairs. These hairs allow the pollinator to crawl into the flower, but then traps it inside. As the pollinator struggles to get out, it is covered in pollen. Eventually, the hairs wither and the insect can crawl back out of the flower, but it may spend a few days inside the flower before being released.

Woolly Pipevine and other Aristolochia species contain a toxin called aristolochic acid, a highly carcinogenic substance as well as a potent kidney toxin. In spite of its considerable toxicity, medicines made from pipevine plants have been used in many different cultures. The name Aristolochia in fact refers to an ancient use in childbirth (aristos = best and locheia = childbirth) and some pipevines are still used in Chinese medicine for arthritis and edema. There is little scientific evidence that these “medicines” do more good than harm, however, and several recent studies have linked ingestion of pipevine to a variety of cancers and kidney failure. It is definitely best to avoid consuming pipevine!

While Woolly Pipevine might be toxic to people and has very few pest species associated with it due to its toxicity, it is a very important food source for Pipevine Swallowtail Butterflies. These butterflies lay their eggs on the leaves and the larvae feed on the leaves as they grow. The caterpillars store the toxins internally to protect themselves against predators, using the aristolochic acid as a weapon against other animals that might want to eat them. You’ll often see small clusters of bright red eggs and reddish or deep purple caterpillars on the leaves and adult Pipevine Swallowtails fluttering around the vines.

We have a healthy Woolly Pipevine plant growing in the Prairie Ridge Nature Neighborhood Garden! On your next visit, head into the main garden entrance under the roof garden and turn right to see the big, fuzzy green leaves covering the fence. Take a close look. You just might see a group of Pipevine Swallowtail eggs or caterpillars lurking underneath a leaf of this fascinating plant!

What Time is it in Nature is a weekly feature highlighting the current plants, animals, and other wildlife at the Musuem’s public outdoor facility, Prairie Ridge Ecostation. Find out more about the natural happenings at Prairie Ridge at our What Time is it in Nature Archive!

Fungus Among Us

A small apartment in the heart of Berkeley was completely filled with a very savory aroma. As guests filed in and left their coats in a pile near the door, they exchanged warm greetings and complimented the chef, Sydney Glassman,(Twitter @fungifoode) on her masterful preparation of a mushroom feast. Glassman, a mycology graduate student at the University of California Berkeley and avid chef, had purchased these mushrooms from an online vendor, but regularly spends her afternoons foraging in the nearby woodlands for wild mushrooms. The mushrooms were ‘Hen of the Woods’ whose scientific name is Maitake frondosa. Glassman marinated them in soy sauce, garlic, honey, and white wine. She then barbequed the mushrooms and served them on top of Mee Goreng, a Malaysian-style stir-fry with vegetables and noodles. You can find her recipe and commentary on the preparation at her blog here. In other posts she details…

iLabs: A Face Mite, Two Researchers and NPR’s Frank Stasio Walk into an iLab…..

I promised information on just how “face mite, Micro World iLab, and Frank Stasio (from NPR’s The State of Things)” are all used in the same sentence.  The best thing I can do to give you the whole COOL story, is to let you see the interview taped at the Museum with the researchers and a teacher involved in the multi-million dollor NSF grant project.

Start watching at 13:56 minutes into the program and it runs until about 33:05.  The microscopic footage of Frank’s mites was taped in our Micro World iLab on our microscope/TV setup.

Our lab’s role in this project is to simply do what we do best — showcase the latest the researchers are up to, incorporating the educational component so the public can understand what it all means, and why it matters!  So in the course of that, Dr. Julie Urban and Dr. Dan Fergus did their…
