Beauty in small things

Lichen are so tiny and so close to the ground that we often ignore them. In close up they are fascinating. They are a fungal host in symbiosis with either algae or cyano-bacteria, which perform photosynthesis , under the protective cover of the fungal host. The component organisms cannot live independently: they need each other to survive.

It is possible to observe roughly how they reproduce, although many of the details are still not well understood. They have a variety of different methods.

The Trumpet lichen, of the genus Cladonia, extrudes tiny trumpet-shaped stalks called podetia:

Cladonia sp. lichen

The little pea-like objects inside the podetia are the lichen “spores”. More properly, they are called soredia, and they are granules of algae and fungi ready to disperse and start a new lichen. Here they are in close-up.

Cladonia sp. lichen

Other lichens have different strategies. This is a ruffle lichen, as I usually find them, on a fallen tree branch. .

Ruffle lichen

This one, however, looked different.

Ruffle lichen

In close-up, those brown patches are shiny:

Ruffle lichen

They are, I think, isidia: small growths of the upper cortex with a shiny surface, and they are the fruiting bodies of this type of lichen. They are brown after rain, they turned black the next day when they were dry,  then brown again after another rainy night.

The lichen below is a species of pelt lichen, Peltigera, that grows on rock, and the reddish brown upcurled lobes are the fruiting bodies:

Pelt species, with reddish brown lobes that are fruiting bodies

The moral of this tale is look closely at your lichen, especially after rain, and you might be delighted. This illustration is from a 1908 German book, entitled “Flora im Winterkleide”, or “Flowers in winter dress”, the artist clearly recognizing the beauty to be found in small things.

The tadpoles are growing apace.  Here are three photos, taken over a total of two weeks, to show you how much they have grown.  If you hover over each photo you can see when it was taken. How long do you think it will be before the legs appear?? I am guessing within a week, fingers crossed.

I have put some of the tadpoles back in the pond, because I thought they needed more room to swim around. I have kept about 16 for now, and I may put a few more back as these get bigger and bigger, But they have a good safe place to live with me, and I am feeding them well, and there are no predators in my kitchen!

In with the tadpoles this morning was a tiny miniature water snail. Here it is next to the dime to show you how small it is:


In close-up it is very pretty. Look carefully at the next photo and look for two things: its eyes, and its mantle. “What’s a mantle”, you ask. Patience, and I’ll tell you!


First, the eyes. They are the two tiny black dots at the base of the tentacles. The mantle is the soft part of the snail, and in some snails, like this one, it has flaps that partly fold out over the outside of the shell.

It walks around using its entire body like one huge foot. Here is a picture of one taken from underneath, when it is walking around on the inside of a glass bowl.

Clothed with scarlet*

[For the adults who don’t read my Frog Blogs, here is a grownup post. I started this one a while ago, and it never got sent because I got distracted, but I thought you might enjoy it anyway, and I updated it with one more scarlet bird.]

American Robins (both sexes) have striking red breasts, and when you see one in a field it stands out from its surroundings in a way that seems to invite attention.

American robins

But then you see one in an apple tree amongst last year’s apples, and suddenly it almost disappears:


Cedar Waxwings, Bombycilla cedrorum,  are handsome birds:

cedar waxwings

And they too were eating the rotting apples as winter refused to relinquish its grip:

cedar waxwings

They are called waxwings after the vermillion tips of their wing feathers, apparently dipped in sealing wax by an unseen hand. You can see them peeping out on the lower of the two birds. Their Latin name Bombycilla means silky tail, because the plumage is especially soft. Wouldn’t you love to be able to touch one? I think it is why so they are very hard to photograph, because the feathers are extremely fine, and my brilliant camera struggles to focus!

And a month later, I saw this stunning Red-bellied Woodpecker, Melanerpes carolinus:


They are not rare, but for me it was my first glimpse. Like all our woodpeckers at this time of year they are drumming like crazy to attract a mate, which makes them easier to find in the woods. Why it is called Red-bellied when it has this flame-coloured head and nape, I cannot imagine.

* The robins in the snowy tree inspired my title,  from the King James’ Bible, Proverbs 31:21

She is not afraid of the snow for her household: for all her household are clothed with scarlet.

Answer to the Mystery Photo from last time: The photo was of a Mayfly nymph. It breathes through a forest of feathery gills:


The beautiful Mayfly that emerges looks like this:

Mayfly, sub-imago, also called a dun.

Back to the tadpole. They are getting really big now. But this morning I was puzzled. In amongst all the big guys was one teensy one. I took a picture of it next to one of the giants:


What has happened? Did this one just hatch very late? Maybe, but I have a different theory.

A week ago, the wood frogs stopped making their quacking sounds, and returned to the woods. Instead, the spring peepers began. Here is what they sound like:

Spring peepers are even smaller than wood frogs. Here is a picture of a full-grown one one on the edge of a hydrangea leaf:

spring peeper

So I think the tiny tadpole is a spring peeper tadpole that was swimming around in my pond, and when I put in fresh water yesterday I scooped it up by mistake and now it’s in my aquarium. Anyway, I’ll keep watching him (or her) and keep you posted.



Deerly beloved ..

We’ve lived in our house in Maine for 38 years. White-tailed Deer are common, but I rarely see them. They eat my flowers, I see tracks, droppings, and signs of browse, but that’s about it.  We have a large field in front of our house, surrounded by woods. Once in a blue moon, a single deer can be glimpsed at the very edge of the meadow, barely out of the woods, but they are very skittish around here, unlike in the suburbs.

On the evening of March 30, four deer emerged from the woods and came some way out into the meadow.


I was, of course, beside myself with excitement. I crept around a corner of the house, and grabbed a few shots, and then something alerted them, and up went the tail:


One was so panicked it crawled underneath the belly of a larger deer,


and off they went:


The tail is a very effective danger signal, even if only glimpsed at speed.

White-tailed deer, Odocoileus virginianus, the only species of deer in New England, can be up to 3 1/2 feet at the shoulder, and weigh up to 400 pounds. A group like this is probably a mother, last year’s fawns, and perhaps even a fawn from the previous year. The fawns are born in June. The following summer, they will leave to forage on their own, but they will return to spend the winter with her, and  perhaps even the following winter.

In New England, deer are often considered pests, and they are widely hunted.  But if they were on the plains of Africa, tourists would badger their guides for photo opportunities of those glorious tails.

P.S. I have since seen a lone deer, on two separate occasions, out in the woods when I was was walking quietly alone.  Perhaps the rarity of my sightings means my particular woods aren’t really very good deer habitat?? I don’t know.

Answer to Mystery Photo from last time: The insect that built itself a house was a Caddisfly. It crawls around on the bottom eating tiny animals and plants. One day, if a fish doesn’t eat it first,  a small fly that looks a bit like a moth will emerge and fly around. 

The tadpoles have grown enormously. Here is how they looked on April 13th, about 1/3 the diameter of a dime:


And here is how they look today, April 18, only five days later, almost as long as the diameter of that same dime:


The tadpoles now have lovely round bodies, and elegant tails with nearly transparent edges that are their fins.  You can sort of see a tiny frog inside. Can you see the eyes?


They swim quite energetically now, here they are:

Here is a new mystery creature for you: what do you think it is? A clue: it turns into something that flies, and it is called after the day of the month when the magic happens and the fly appears …  Answer next time.

Mayfly nymph

And a poem for you: you can read it out loud, or even sing it!

Five little tadpoles swimming near the shore.

The first one said, “Let’s swim some more.”

The second one said, “Let’s rest awhile.”

The third one said, “Swimming makes me smile.”

The fourth one said, “My legs are growing long.”

The fifth one said, “I’m getting very strong.”

Five little tadpoles will soon be frogs.

They’ll jump from the water and sit on logs.

Whaling and the Gray Whale Population

[This is not my usual nature post. Rather than discussing whaling in my other gray whale posts, I though I’d do an entirely separate one. Some people are very interested, others would prefer to move on. Up to you.  This is my last whale post. Next time I return to Maine.]

The Makah Indians of the Pacific Northwest have traditionally hunted grey whales from canoes, as shown in this 1883 drawing:


This photo was taken in 1910.


The numbers they caught were small, and a healthy gray population was not heavily impacted.  In the North Atlantic, however, countries like Iceland hunted them from at least the 1300’s and for whatever reason by the late 1700’s gray whales had disappeared from that ocean.

In the Pacific, when the European settlers came and started to catch gray whales on an industrial scale, things changed. One pivotal event was Captain Charles Scammon’s discovery of the calving lagoons.


Born in Pittston, Maine in 1825, about 90 minutes from where I now sit, he discovered Ojo de Liebre lagoon (now called Guerrero Negro), and caught whales there from around 1857, and then in San Ignacio lagoon (where I was) two years later. Within a few years they had killed so many whales that they had pretty much emptied the calving lagoons. Later in life Scammon wrote an apparently unsuccessful scientific book about whales, which is now ironically highly thought of.

 Scammon, Charles (1968) [1874]. The Marine Mammals of the North-western Coast of North America: Together with an Account of the American Whale-fishery. Dover. ISBN 978-0-486-21976-9.

In Baja California, the whalers were often based on land and went out in small boats. It was a dangerous occupation; the gray whales frequently overturned the boats, or towed them for long distances.

Moby Dick swam swiftly round and round the wrecked crew. (Page 6

Nonetheless, they caught whales in huge numbers. Between 1845 and 1874 it is estimated that whalers killed over 8000 whales, a disproportionate number of which were mothers with calves.  Dead calves were not counted, so the actual numbers were much higher.

It looks rather charming here, but the reality was quite different.


By 1875, industrial-scale whaling of gray whales was over, and it is thought that no more than 1-2000 whales were left alive, though one estimate was that only 160 remained. In the 20th century only 4 countries continued to hunt gray whales: the USA, USSR, Norway and Japan. They used cannon-fired explosive harpoons, and killed a total of 2407 between 1910 and 1946.

Whaling for gray whales was banned for commercial purposes in the US and Norway in 1937, in the USSR in 1946, and in Japan in 1951. Aboriginal peoples have special quotas for subsistence whaling, about 160 whales per annum worldwide. In 1971, the Mexican government protected the calving lagoons as marine wildlife sanctuaries, and in 1993 they became part of the huge Vizcaino Biosphere Reserve, a UNESCO World heritage site.

Astonishingly, since whaling stopped and protection began, the Eastern Pacific gray whale population has rebounded to what are thought to be close to their original numbers of around 26,000, and the Eastern Pacific population of gray whales has now been removed from listing under the US Endangered Species Act. They are still protected by CITES.

It seems, then that we are somewhat atoning for our barbaric treatment of gray whales in the 19th century by finally affording them the protection that they desperately needed and deserved. It is heartening to see that recovery on this scale is indeed possible.


I am indebted to James Sumich’s wonderful 2014 book E. robustus: The Biology and Human History of Gray Whales. 

The article below came out this month, and is an authoritative overview of what has been done, can be done, and should be done to rebuild marine life in general.

Last time’s Mystery Photo answer: It is a mosquito larva. In two months it will emerge from the pond  and a mosquito will come out and fly away. Or maybe a tadpole will eat it first?

The tadpoles are flourishing: many of them have come out now and are swimming around the bowl.  It makes them very hard to photograph! They like the edges of the bowl:


And close up they now look like this, with a proper body and a tail. They are about 1/4″ long,  and their body is about the size of a grain of rice.


They often lie still, resting, but if the water moves, they swim around:

I put one in little bowl on its own so you could see how it swims. When we swim, we kick our feet up and down, but a tadpole moves its tail very fast from side to side. You might have to watch this very short video more than once to see what it does.

Once I’d taken the video, I put him back with his friends in the big bowl.

Here is a new mystery creature for you, from the pond. It looks like a collection of bits of reed, but in fact it has been collected by the larva of an insect, to protect itself from predators. From the safety of its armor, this one is venturing halfway out to investigate its surroundings:


Do you know what the insect is?? Answer next time!

My next post won’t be till the tadpoles have either grown much bigger, or are changing in interesting ways.  Up till now they haven’t eaten anything, but soon they will be hungry, and I will tell you some time what they like to eat. I’m not sure how long it will take for them to grow, but meanwhile I will go on doing posts for grownups about other things entirely, but all about nature, and maybe you would like some of the photos in those too?

Things are moving fast!! I don’t think these eggs are going to take 20 days to become tadpoles!

One day after I put the eggs in a bowl, they had already begun to transform. Last time, they looked like black dots, or periods.  But now they look like commas. I put a few eggs in a smaller bowl so I could take a close-up photo more easily:


You can sort of see a tail, and two bumps on each side of the head that will become eyes, or maybe gills. One egg doesn’t seem to be growing at all. There may be something wrong with it, or maybe it is just a little slower than the rest?

The next morning, the tadpoles had started to grow longer tails, and gills! Can you see the little feathery things sticking out on each side: those are called gills.


Tadpoles don’t put their heads above water to take a breath. Just like fish, they breathe water. When the water flows over their little gills, they are able to get oxygen from the water, just like our lungs get it from the air we breathe. Clever, huh?

And the really amazing thing is that they are starting to wriggle inside their jelly capsules. I’m going to try and get a video for next time.

There are other things living in my pond. Do you know what this is?? Try to guess. Clue: it is very, very tiny, smaller even than the frog’s eggs. The answer will be in the next blog.



The bitter end

The start of spring is in fact a very hard time for most wildlife. The winter food sources are almost completely exhausted, and nothing new is yet growing. It snowed again last night, April 9th.

The chickadees have been here all winter, and at this point they will explore any possible food source. This one seems to have found some insects in a knothole in a telegraph pole:


And this one has found something under the lichen on an old apple tree:


These beaver, in a pond with at least two active lodges, were busy some time before the last snowstorm (since there is snow on top of the felled tree), eating the cambium under the bark. They are venturing out now, I have found active scent mounds that they use to mark their territory. Their lodge is visible in the background:


Meanwhile flocks of turkeys are around, the males proudly displaying early in the morning. The three coruncles dangling from their wattles turn bright red with blood when they are excited…


It now gets light around 6.30am, and I am being woken every morning by noisy turkey dating sessions.

Life goes on.
