It looked very nice in the pond, ready for a photo!

A pair of Northern Green Frogs in the shallows of the Shawmere River off of Highway 101 West located in the Township of Murdock in Northeastern Ontario Canada
The northern green frog (Lithobates clamitans melanota) is a subspecies of the green frog, Lithobates clamitans. It is native to the northeastern North America and has been introduced to British Columbia. Its mating call sounds like the single note of a plucked banjo.

Green Frog
My bride asked, "How did you get him to stay still? "Frogs stay still when they're sad," I replied. "Doesn't he look unhoppy to you?"
The Green Frog occurs in southern parts of central and east Canada as well as the eastern half of the United States. Green frogs are usually found in or near shallow permanent wetlands such as swamps, lakes and streams. The diet of adults consists of a variety of small invertebrates including insects and molluscs whereas jeuveniles (tadpoles) feed on decaying plant and animal parts, algae, micro-organisms and assorted organic matter suspended in water. Hibernation is in water of sufficient depth to avoid freezing in winter.

Right before sunrise in the Richmond lagoons I had a few encounters with the slightly rare blue morph Green Frog. This is a variation caused by deficiencies in the yellow pigment cells, called xanthophores. The blue pigment cells that combine with the yellow, called iridophores, are present, causing blue light to reflect.
There is no scientific calculation of the frequency of these blue morphs, but I have seen one to two percent cited in a few places.
In this case, I was so preoccupied with the blue that I omitted the other field marks that help distinguish the Green Frog from the Bullfrog: the dorsal ridges that run only part way down the frog’s back. Most of the other colouring on Green Frogs is variable, including being partly brown, yellow or white undersides, etc. The males have tympana larger than their eyes, while the females are roughly the same size; males also have bright yellow throats in breeding season.
I was also preoccupied with not stepping on it. Green Frogs move significant distances out of the water, hunting for small land-based insects. In the early morning one has to be extremely careful, as frogs and snakes and even turtles, hunting in the low early light, will freeze in the camouflaged setting. The second cup of coffee in the dark before heading out helps in more ways than one.
This is a very common frog - blue morph excluded - in this part of the world, and its ‘gunk’ call, either singularly or a series, is a common early morning or late evening sound from wetland areas.
The Northern Green Frog is native to northeastern North America and has been introduced to British Columbia.
The Northern Green Frog looks very similar to the Bullfrog, but you can tell them apart by checking for ridges proceeding from the Northern Green Frogs eyes.
I've uploaded video footage of this frog here: www.youtube.com/watch?v=GxbLzJJdQH0

Les grenouilles vertes font sans aucun doute partie des batraciens les plus souvent observés et les mieux connus du grand public. Au printemps et en été, leur chant retentit aux abords des points d’eau, de jour comme de nuit. Durant la journée, les grenouilles vertes se chauffent au soleil sur la berge, d’où elles peuvent sauter dans l’eau pour se réfugier en cas de danger. Les palmures bien développées des pattes postérieures font d’elles d’excellentes nageuses. Les grenouilles vertes d’Europe forment un groupe comptant plusieurs espèces et variétés proches les unes des autres, dont deux seulement sont indigènes : la Grenouille de Lessona, Pelophylax lessonae Camerano 1882, et la Grenouille verte proprement dite, Pelophylax esculentus Linnaeus 1758. La Grenouille de Lessona est une espèce à part entière, tandis que la Grenouille verte est une espèce hybride, issue du croisement entre la Grenouille de Lessona et la Grenouille rieuse, Pelophylax ridibunda Pallas 1771, à l’origine une espèce exotique. Celle-ci a en effet été introduite au 20e siècle dans plusieurs régions de Suisse.

Green frogs are undoubtedly one of the most frequently observed amphibians and best known to the general public. In spring and summer, their song resounds near water points, day and night. During the day, green frogs bask in the sun on the shore, where they can jump into the water to take refuge in case of danger. The well-developed webs of the hind legs make them excellent swimmers. The European green frogs are a group of several closely related species and varieties, of which only two are native: the Lessona Frog, Pelophylax lessonae Camerano 1882, and the Green Frog proper, Pelophylax esculentus Linnaeus 1758. The Frog de Lessona is a species in its own right, while the Green Frog is a hybrid species, resulting from the cross between the Lessona's Frog and the Common Frog, Pelophylax ridibunda Pallas 1771, originally an exotic species. It was indeed introduced in the 20th century in several regions of Switzerland.
Just a little green frog on the lake, from the past Spring. Soon they'll be around again.
Waiting at home for better temps and no rainy days. I miss my walks on the parks! Thanks everybody for the kind comments!
Green frog
A mature frog is a carnivore. It is a fantastic predator that eats everything that moves and that is not too big to swallow. It eats insects, crickets, spiders, caterpillars and snails. It catches its prey with its long tongue, which can grow to over 30 cm. long. Sometimes the prey is caught by jumping towards it. The food is swallowed whole and digested in the stomach.
In visiting birding locations before or at sunrise, one has to be mindful of all the creatures on the ground, especially around water. I saw some movement in the grass and lay down on my stomach as this Green Frog emerged. It is the first time I have seen a Green Frog with a bit of the blue morph coloration - not crazy rare, but certainly uncommon. The blue morph Green Frog gets its blue from a depletion or absence of the yellow pigment that combines with the blue pigment to reflect light and form the normal green. First light and a neat frog - a fine morning.
The frog was rather far from me, so I had to crop quite a bit. There is a tadpole close to the frog and I think one on the very right side. This was taken at the Grand Ideas Garden in Grand Rapids.
Green frogs live wherever shallow freshwater ponds, road-side ditches, lakes, swamps, streams, and brooks are found. Green frogs can be found in vernal pools and other temporary bodies of water, but will usually not breed in them. This species is very opportunistic and is quick to colonize new water bodies such as swimming pools and artificial ponds. Most often seen resting along the shore, they leap into the water when approached. By inhabiting an ecotone, in this case the terrestrial and aquatic habitat boundary, green frogs (and other aquatic ranid frogs), by employing a simple leap, leave behind their many and faster terrestrial enemies that cannot similarly cross that boundary.

The Green Frog (Lithobates clamitans) is a large, frog distinct tympanum and prominent dorsolateral ridges. It may be green, bronze or brown, or a combination but is typically green on the upper lip. The belly is white with darker lines or spots. There may be some irregular spotting on the back. It is distinguished from other frogs in that the dorsolateral ridges run only partway down the back and do not reach the groin. The hind legs have dark bars. Males have a bright yellow throat. The male tympanum is twice the diameter of the eye, whereas in females, the tympanum diameter is about the same as that of the eye.
