The Trilling of a Frog

Save The Frogs Day April 29

“If we can discover the meaning in the trilling of a frog, perhaps we may understand why it is for us not merely noise but a song of poetry and emotion.” – Adrian Forsyth

In the plains and parkland region of Saskatchewan are several species of frogs which can be found around the wetlands, marshes, rivers, streams, and “prairie potholes.” The number of species observable increase during the cyclical years when Saskatchewan has a higher water table. Saskatchewan, experiences a temperate climate, which cycles between drought and high moisture years. Winnipeg locates at the confluence of the Red and Assiniboine Rivers. During the years when the Red River produces great floods through North Dakota, and Manitoba, those are also years when the water table is high in Saskatchewan and communities of Saskatchewan also experience flooding. Historically, there have been high water levels during the years 2011, 2009, 1997, 1996, 1979, 1974, and 1950.

Saskatchewan species of frogs include; Canadian Toad Anaxyrus hemiophrys, Great Plains Toad Bufo cognatus, Plains Spadefoot Toad Spea bombifrons, Boreal Chorus Frog Pseudacris maculata, Leopard Frog Rana pipiens, Wood Frog Rana sylvatica. Diane Secoy limits the The Plains spadefoot and Great Plains toad to the southwestern corner of Saskatchewan, the area formerly known as “Palliser’s Triangle.”

Biologists study the ecology, life history, osteology, and mating calls of the these amphibians. The evolutionary history is determined by examining the distributions, ecology, cranial osteology, and mating calls. In the field, colouration is noted, along with webbing between fingers, shape of the snout, size, distinctions of thighs, shape of vocal sac, shape of maxillary processes, for instance to determine geographic variations. The tadpoles are also examined for ventral fins, mating calls, colouration, tail, snout, teeth.
Frogs do have an olfactory sense, and can sense chemical changes in the air. The presence of amphibians in an ecosystem, is a good indicator of the health of the biome. Tadpoles can use the chemical scents as a method to be aware of predators or food. The particular marsh, or wetlands area where a tadpole was born possesses its own unique perfume or scent, to which the frog is also drawn towards in the final life cycle. At the top of the frog’s mouth is the jacobson’s organ, which is how a frog detects scent. A frog will open and close their mouths to activate their jacobson’s organ in an effort to locate food.

On studying amphibians, not only is it important to reflect upon where are frogs, and toads in winter-time, but also where are frogs and toads in the summer-time during droughty years?

When discovering a Saskatchewan amphibian could you tell a toad from a frog?

Do you know what is the life cycle of a frog (or of a toad) as if related by the creature itself?

So what can you do on “Save The Frogs Day April 29?” The most important thing, would be to Learn about the Frogs of Saskatchewan!

“There were frogs all right, thousands of them. Their voices beat the night, they boomed and barked and croaked and rattled. They sang to the stars, to the waning moon, to the waving grasses. They bellowed long songs and challenges.” – John Steinbeck

Join In – it is not meaningless!

“All Canadians are invited to join in supporting and implementing this strategy for the benefit of the Loggerhead Shrike Prairie subspecies, and Canadian society as a whole” ~ Environment Canada

“I believe in oneness of mankind and of all living things and in the interdependence of each and all. I believe that unless we play fair to the Earth, we cannot exist physically on this planet.”~Richard St. Barbe Baker.

It is not at all meaningless to speak about the Prairie Loggerhead Shrike (Lanius ludovicianus excubitorides). This unique small passerine bird is listed as threatened / critically endangered as the population has been steadily decreasing since the 1960s.

The Loggerhead shrikes love scattered shrubby growth, and will nest in Caragana, Manitoba Maple, and thorny vegetation such as Buffaloberry shrubbery. The Shrike breed along shelterbelts and riparian areas of the prairies. In this south west sector of the city of Saskatoon, botanists have confirmed that this species is documented for this region wherever there may be wetlands combined with open areas and tall shrubbery.

In order to thrive, and be resilient, the Shrike requires an open grasslands area to forage with elevated perches or lookout points about 4 meters high upon which to sit to facilitate their hunting activities.

The Loggerhead Shrike is quite unique in its dietary habits, as it does not confine itself to seeds, berries insect grub and larvae, but as a carnivorous bird, will capture amphibians, lizards, small mammals such as mice, and small birds. Due its small size, it impales its prey on barbed wire or the thorns of the Buffaloberry bush, which grows around the Chappell Marsh and West Swale wetlands. Though, the main food are grasshoppers, beetles, and rodents. It is only when these are hard to find, that the Loggerhead Shrike will forage for other animals.

How to identify the Loggerhead Shrike:
The wings are coloured black, with a white patch, and the head is quite unique with a mask across the eyes similar to a raccoon. The main colour of the Shrike is grey, with a white or pale breast. Shrikes are about 9 inches in length, and weigh in at 45-60 grams. The Loggerhead Shrike migrate here in March and April leaving after the breeding season from September to November. These birds will migrate nocturnally.

Outlook for the Shrike
Though it is truly unknown what has caused the numbers of the Loggerhead Shrike to plummet, ornithologists hope that by studying the birds and their habitat, the cause for their decline can be ascertained. Currently listed as a threatened species by Committee on the Status of Endangered Wildlife in Canada,  COSEWIC. it is a mandate to place the environment of the Loggerhead Shrike safe from destruction by conversion or development which may alter their prey populations. Scientists have also decided to place the Prairie Loggerhead Shrike as Schedule 1, Threatened under the federal Species at Risk Act (SARA). It is also interesting to note that the International Union for the Conservation of Nature declared temperate grasslands the world’s most endangered ecosystem. * “Grasslands can also showcase how people and nature can coexist,” said Dan Kraus, a Nature Conservancy of Canada (NCC) scientist, “Among the last places on Earth to shelter grasslands at a meaningful scale are the grasslands of North America’s Great Plain…Endangerment comes down to risk — the risk of losing a species, habitat or ecosystem for future generations. *

In the south west sector of the city of Saskatoon, it is a relief that remnant native grassland remains. Additionally, the Richard St. Barbe Baker Afforestation Area affords wetland plant communities. The West Swale which passes through the large open wetlands and Chappell Marsh features many small scattered wetland areas, with more than adequate habitat and foraging for aquatic fauna, with belts of native and modified grasslands.

The Loggerhead Shirke, Lanius ludovicianus excubitorides during its breeding seasons, ie a “breeding Bird is characterized by: territorial behaviour; calling to competing male, mate or young; singing; courtship displays; carrying food or nest materials etc., and; presence of nest or young found incidentally. Between May 1 – Aug 15, the Loggerhead Shrike is protected 50 meters from low disturbance activity such as walking, and is protected for 250 meters from medium disturbances such as driving, and 400 m from roads, drilling, and other such high disturbance activity according to the Ministry of the Environment for Saskatchewan.

It is interesting to note how the City of Saskatoon’s citizens and residents regards conservation expectations or indifference to wildlife species such as the Prairie Loggerhead Shrike and their habitat. As Environment Canada states, “Success in the recovery of this species depends on the commitment and cooperation of many different constituencies that will be involved in implementing the directions set out in this strategy and will not be achieved by Environment Canada, Parks Canada Agency, or any other jurisdiction alone. All Canadians are invited to join in supporting and implementing this strategy for the benefit of the Loggerhead Shrike Prairie subspecies, and Canadian society as a whole.*

“Kind people have been expressing superlatives on my work. But I can assure you that anything which I have been able to achieve has been team work. We have a motto in the Men of the Trees. TWAHAMWE. It is an African word meaning ‘pull together’ and I pass this on to all those concerned with conservation in this country. I would like to call you to silence for a moment with the words of Mathew Arnold:

“Calm soul of all things, make it mine,
To feel amidst the City ‘s jar
That there abides a peace of thine
Men did not make and cannot mar. ”
