Green Frog In Maryland

Posted May 21, 11 -Filed Under Nature: plant and animal identification, children's activities (recycled materials), seasonal: spring, seasonal: summer | Leave a Comment

Green Frog (Rana clamitans)

I’m participating in a program called Maryland Amphibian and Reptile Atlas (MARA). MARA is a project run by the Natural History Society of Maryland (NHSM) and the Maryland Department of Natural Resources (MDNR); it is a five-year (January 2010 -2014) atlas of the amphibians and reptiles of Maryland. Amphibians and reptiles are collectively known as “herpetofauna” or “herps.”

I’ve been learning my local herps in the last few years and I’ll share some pictures of herps that I find on my property or in my neighborhood.

Green frogs are sometimes confused with bull frogs. You can’t go by color because their color varies. Look for the prominent dorsolateral ridges that go down the back but not all the way.

Note the large external eardrum called a tympanum (the circle behind the eye).

This picture illustrates relative size.

I love its eyes!

P.S. I believe this is a female because she lacks a yellow throat and her tympanum is not larger than her eye.

Cool Thumb-controlled Watering Pot Made With Recycled Materials

I got the idea to make these thumb controlled pots from the pottery ones I’ve seen at Historic Williamsburg. The original earthenware “thumb pots” were used in 17th and 18th century English gardens. I reproduced this clever watering device using salvaged plastic bottles and jugs. It is ideal for watering delicate seedlings. I use this watering pot all the time now.

To Make:

Find a suitable “pot.” I love using maple syrup containers but I was successful making other smaller pots with smaller plastic milk bottles. The smaller bottles are easier for children.

Drill a hole in the center of the cap of your container. I used a 7/32nd drill bit. Next, drill small holes in the bottom. I used a 1/16th drill bit. When using softer plastic containers, it is possible to poke holes instead of using a drill. Make sure the cap is on tight; otherwise the water will not stay inside.

How it works:

It works similar to holding your thumb over the top of a drinking straw.

1. To fill your thumb pot, place into a bucket of water. Do not cover the hole in the top.

2. Hold your finger over the hole in the cap to prevent water from escaping the bottom as you lift.

3. Continue to hold your thumb over the hole as you lift.

4. Take your thumb off the hole when you are ready to water your plants. Removing your thumb allows the water to gently stream out the holes on the bottom.

Sweet Spring Basket Craft: Wheat Grass Growing In Recycled Tray

Posted Apr 18, 11 -Filed Under children's crafts (recycled materials), crafts (recycled materials), garden (gardening info and eco-friendly project ideas), gifts from recycled materials, holiday crafts: Easter, plastic, seasonal: spring, use for natural stuff: vines, sticks..., use for yarn scraps | 3 Comments

This is a craft that is good for large groups of kids like school classes because the mushroom trays can be saved by the parents and the overall project will be very inexpensive. The handle for your “basket” can be made with a lot of different materials but I like the natural ones best. The photos show a basket handle made with a twisted piece of drift wood. You can grow grass seeds or wheat grass berries.

I waited too long to take these pictures: the grass is getting too tall. When we are done enjoying our grass baskets, I let my chickens enjoy the greens ! No wasting.

Note: This project is meant to be a centerpiece and is not meant to be carried around by the handle.

Follow this link for tips on growing wheat grass.

One more note:

I like growing wheat grass because it doesn’t take a huge amount of planning ahead. The plants will sprout in just a few days. When I grew the wheat grass in these mushroom trays, I soaked the seeds overnight and then put them on top of the potting soil, watered it, covered the tray with plastic for the first day or two and then watered only as needed. -Very easy child project.

Frog Hunting In Maryland: The Northern Cricket Frog

Posted Mar 22, 11 -Filed Under Nature: plant and animal identification, children's activities (recycled materials), seasonal: spring, seasonal: summer | Leave a Comment

It is spring and time to look for frogs. Yesterday, my daughter and I went for a nature walk in the woods around our house. During our adventure, we found this frog. It is a cricket frog, Acris crepitans. Cricket frogs are non-climbing tree frog. I’ll be sure to look for their eggs during their breeding season (May through July).

This cricket frog is on a child’s hand.

Identification:

They vary in color but often have a dark triangle present between the eyes and a Y-shaped stripe on their backs.

Fun With Cattail Spikes

Posted Mar 4, 11 -Filed Under children's activities (recycled materials), seasonal: spring, seasonal: winter | Leave a Comment

When exploring a wetland with my daughter, we came upon some cattail plants (Typha sp.) When I saw them, I remembered how fun they can be. We had a pleasant time together discovering or re-discovering the amazing qualities of cattail spikes.

You have got to try this! Find a cattail flower spike in winter or early spring when last year’s flowers produced a sausage-like thing that is magic: or something close to it. Try pulling a handful off and hold it tight, then watch when you open your hand. It will explode into a soft landscape full of tiny seeds. Each seed has a bit of fluff attached; the purpose is to allow wind to carry the seed off to new locations.

All I ask is that you don’t play with all the spikes. Leave most of them alone. Did you know that some birds use the fluff to line their nests?

Raising Tree Frog Tadpoles (MD, USA)

Posted Aug 17, 10 -Filed Under Nature: plant and animal identification, children's activities (recycled materials), seasonal: spring, seasonal: summer, use for vegetable scraps | 22 Comments

If you have kids, raising tadpoles into frogs is a must. With not much effort you can witness the fascinating metamorphosis of a tadpole into a frog. Here is a tree frog we raised in the summer of 2004.

Gray tree frog found on my house (which is green) in southern Maryland 2008.

Mini Pond -2004

We have a galvanized container that I got at an antique store that doubles as a mini deck pond. When it rains we often hear one or more male tree frogs calling for a mate. They usually get together at night but we’ve seen them on really rainy days. In the morning we see eggs in our pond: lots of them. It doesn’t take long before you have all those little tadpoles swimming around. At this point, we get a few of the tadpoles to raise inside. I find that if the weather is really hot, the tadpoles all die. Hence, for better results, we bring some inside for raising. The tadpoles in our mini deck pond, if conditions are good, will eat mosquito larvae growing in the “pond”. Therefore, I don’t have to worry about creating a mosquito problem. The tadpoles will also eat algae- the green stuff growing on the sides of your pond. Your pond will stay cleaner looking. They will also resort to eating smaller tadpoles. This sounds pretty harsh but in doing so, at least some of the tadpoles will make it to adulthood.

Home for tadpoles

We kept our tadpoles in various large glass containers over the years. I like to limit the number of tadpoles because you don’t want to overcrowd them. The number you raise will depend on the size of the jar or tank you use

Change the water:

Freshen the water by dumping about half out and replacing it with fresh water. I have well water but if you have city water, you probably have chlorine to worry about. The chlorine will kill your tadpoles so set out a pitcher of water for a day or two in preparation to adding it to your jar of tadpoles.

Feed your tadpoles:

Your jar pond should have sunlight so the algae can grow. They love to eat the algae that grow naturally but there will not be enough in your little “pond” so you will need to feed them.

Don’t add so much food that the water gets all dirty looking. Feed as needed. I’ve successfully raised tadpoles on lettuce. I chopped it up then boiled it for a short time. (I’ve since read that boiling it first isn’t necessary.) After that I’d either pour off the water and freeze it or make portions in ice cube trays: the lettuce is frozen in the ice. Either break off bits of your frozen lettuce or drop in an ice cube when necessary. I’ve also feed them leftover fish food that I didn’t need any more. They loved that too.

I recently found the following link. It provides additional information about keeping tadpoles and is definitely worth checking out (no pictures though).

http://frogs.org.au/x/media/cs-lentic.pdf

When they start to grow front legs, you will need to cover your jar with cheese cloth or mesh of some kind so they don’t escape into your house. There needs to be something for the frog to climb onto- out of the water because you don’t want your new frog to drown. Release your tree frog back into the wild after metamorphosis takes place.

The whole process will take a little over two months if you are starting with eggs.

Check out the mouth on this guy!

This tadpole is clearly trying to go unnoticed.

Back legs at last!

Almost done!

How cute is that!

Make A Micro Pond Observatory For Learning And Fun: Damselfly Observation

Posted Jun 12, 10 -Filed Under Nature: plant and animal identification, children's activities (recycled materials), seasonal: spring, seasonal: summer | Leave a Comment

In this photo is a damselfly larvae (arrow points to it) and to its left is a salamander larvae (more on it in another post).

How interesting to discover the world living in pond water. When I scooped up some pond water and brought it home for observation, I didn’t know that there was a damselfly larvae in it; we just wanted pond water full of tiny aquatic insects to feed our salamander larvae (more on this salamander larvae later). We were delighted when it crawled out of the water and soon emerged as an adult damselfly.

To make your micro pond you need only to find a container, gather some pond water, and add a stick and/or rock. We used a large glass cookie jar. We broke the top sometime back; it is 10.5 inches height and about 9 inches across (see picture). But you can use what you have or can find; think outside the box. Use an extra large pickle jar (ask for one at a sandwich shop; that’s what I did), find a secondhand fish bowl (not hard to find at thrift stores), or use a large glass carafe from a coffee maker (one that the coffee maker itself is broken but not the carafe).

The idea is to keep your micro-pond around long enough to allow things to grow. We plan to keep ours for most of the summer or until our frogs metamorphose. Some frogs like bull frogs and sometimes green frogs hibernate at the bottom of ponds and therefore will not finish metamorphosing until the following summer. Bull frogs will sometimes take 3 years. If tadpoles don’t complete their metamorphosis, we will let them go before the fall (more about keeping tadpoles in another post). To keep the critters in your micro- pond alive you must add new pond water to it every week. Take out some of the old water at this time. Basically, the tiny things swimming around are food for the larger things. 

According to this website: http://www.dnr.state.md.us/bay/cblife/insects/damselflies.html, larvae feed on other insects and small invertebrates while adult damselflies feed on mosquitoes and other flying insects.

The three “tails” at the back are called the caudal lamellae. These are the insect’s gills.

The skin that the insect leaves behind after turning into a winged adult damselfly is called an exuvia.

Here is a snapshot of the adult damselfly. You will want to put a screen across the top of your pond if you suspect a damselfly larvae will be emerging soon. I was unprepared and this guy got away in my house.

More about this soon.

Explore A Stream: You Might Discover Lampreys

Posted May 23, 10 -Filed Under children's activities (recycled materials), seasonal: spring | Leave a Comment

In an earlier post I misidentified this lamprey as an American Eel. I’d like to make the correction here.

On a hike along a stream (Maryland USA / March 2010) we found several brook lampreys swimming around. There are three species of lampreys in Maryland: Sea Lamprey, Least Brook Lamprey, and American Brook Lamprey. This one is a Least Brook Lamprey or an American Brook Lamprey. Both or these brook lampreys are non-parasitic. Sea lampreys use their disk shaped mouth to attach themselves to fish and drink their bodily fluids and blood. Brook lampreys do no do this. I believe we came across some lampreys spawning. After they spawn they die soon afterward.

You can find some interesting things out there!

Look For Amphipods The Next Time You Are Visiting A Beach

Posted May 4, 10 -Filed Under Nature: plant and animal identification, children's activities (recycled materials), seasonal: spring, seasonal: summer | 2 Comments

Summer is on the way and many families head to the beach. Make a special effort to seek out amphipods. They are rather interesting little creatures.

You can find amphipods such as this big-eyed beach flea on or in the sand. This picture was taken in Southern Maryland. They like to feed on decaying vegetation that washes up on the beach.

This amphipod is commonly called a beach flea. Don’t worry though, they don’t bite. They feed only on organic debris. If you get flea bites from a visit to the beach, you got them from common fleas (like the kind you have on your cat or dog). Common fleas can also be found on beaches.

Big-eyed Beach Flea Talorchestia megalophthalma

Have you ever come across any of these funny looking things with excellent hopping ability while at the beach?

More about amphipods:

About 7,000 species of amphipods have so far been described.

Amphipods are found in almost all aquatic environments.

Making Fun Gourd Bird Houses

Posted Apr 23, 10 -Filed Under Nature: plant and animal identification, crafts (recycled materials), garden (gardening info and eco-friendly project ideas), gifts from recycled materials, reuse hangers, coat, seasonal: spring, use for natural stuff: vines, sticks... | 6 Comments

Attract birds to your yard with home-made environmentally friendly gourd bird houses. You can make several in an afternoon and have fun doing it. You can keep it simple or you can tap into your playful side.

How to:

Getting the gourd

Ask around at local farms and farmer’s markets. There is a good chance that you will find some already dried. If so, you can start making your birdhouse right away.

If you plan ahead, you can grow your own gourds. How cool would that be?!

Drying the gourd

The easiest way to dry your gourds is to spread them out in a box and place them in the garage for the winter. They are going to mold on the outside a bit no matter what you do: no worries. Check on your gourds: if a gourd is rotting (i.e. the shell is getting soft), you should discard it so it won’t spoil the others.

Cleaning your gourd

Some people soak their gourds in a bleach solution to remove the mold. I don’t like to use bleach more than necessary and I find it isn’t necessary here. Either way you will need to scrub and wash and even scrap your gourd clean. It takes a bit of elbow grease. Don’t you like the patterns left on its skin? 

Drilling the holes

Use a drill bit for the size you want your birdhouse hole to be. You can find suggested birdhouse hole size for specific birds online. I used a two inch (diameter) hole for the birdhouse seen here.

I also drilled small drainage holes in the bottom of the gourd just in case rain should get inside.

Finished birdhouse has linseed oil applied.

Finishing the birdhouse(s)

Find salvaged paint (your own or someone else’s leftover paint). I found a small container of exterior paint at the Restore and used that to paint one of my birdhouses. I also used the two hole pieces, from the door openings which I painted white, for the eyes of this amusing birdhouse. I used Gorilla glue to attach them.

For my other gourd, I applied linseed oil. Linseed oil is a natural oil used as a wood preservative and is made from flax seeds. Use a rag to rub on a thin layer of oil. If using multiple coats, allow to dry between applications. The linseed oil will give the gourd a polished look and will help repel the rain. Linseed oil doesn’t preserve your birdhouse for as long as other products but you can compost the old and make a new.

Hanging the gourd birdhouse

Use a piece of scrap rope/ string or even an old shoe lace to hang your finished birdhouse. If you want to be fancier, you can bend an old coat hanger into a hook. First drill two holes to slide the wire through.

This purchased birdhouse has an orange stain on it. Stain is nice because it gives the birdhouse a color but the natural look of the birdhouse shows through. The diameter hole for this birdhouse is 2 inches. I placed this orange gourd birdhouse outside my front door where it is sheltered by our house roof. It is hanging on the wall of our house. Despite the fact that wren birdhouse hole sizes are recommended to be much smaller, a pair of wrens moved into our gourd birdhouse and successfully raised six chicks last summer (2009).

 I hope they will be back, I do love wrens. On a side note, I’ve seen wrens go in/ out of our gourd birdhouse in the winter. I assumed that it or they were seeking shelter from the cold. This is one of the baby birds that left the nest that day. So cute!

This is a snapshot of the mother or father wren that worked tirelessly feeding all those babies!
