American Bullfrog (Lithobates catesbeianus).
Prey motion elicits feeding behavior. First, if necessary, the frog performs a single, orienting bodily rotation ending with the frog aimed towards the prey, followed by approaching leaps, if necessary. Once within striking distance, the bullfrog begins its feeding strike, which consists of a ballistic lunge (eyes closed as during all leaps) that ends with the mouth opening. At this stage, the fleshy, mucous-coated tongue is extended towards the prey, often engulfing it, while the jaws continue their forward travel to close (bite) just as the tongue is retracted. Large prey that do not fit entirely into the mouth are stuffed in with the hands.

Every spring, when night time temperatures begin to rise and humidity allows, Common toads start a dangerous mass migration from the winter quarters to their aquatic spawning sites. Often these animals have to overcome man made barriers - especially roads - cutting through their habitats. Some animals fall into storm drains and even more are run over by cars and bikes.
Permanent underpasses and temporary fences, the latter maintained by volunteers who carry cought animals over to the other side, are ment to mitigate the loss of lives. Nevertheless public awareness is still important, as it is impossible to cover all relevant routes.
Many other species face the same hurdles but via their large numbers Common toads have become the face of amphibian road mortality in Europe. Photographs documenting these migrations and illustrating the dangers as well as the neccessary conservation work have by now become their own little genre to which I very much wanted to make my first contribution this year.
If you want to help, drive carefully, avoid roads with heavy migration and consider joining your local toad patrol.

These European common toads mating in an urban setting just a couple hundred meters from my flat made for my first shot of 2020. Broken up by suboptimal weather and a sudden week of night frost the amphibian migration and reproductive period was photographically less productive than I had hoped for. However it was interesting to experiment again with night time photography, trying a torchlight instead of my twin flashes. Besides I haven't had much opportunity for using the Sigma 8-16mm until now.
However with this shot there was a bit of digital retouching of distracting elements involved. I'm not too big a fan of digital processing, convinced that the principal part of photography should occur in camera. But I'm getting more comfortable using GIMP to touch-up now and there are otherwise presentable pictures that would greately suffer from easily fixable issues. If the fixed-up parts are apparent to you, let me know in the comments.
Given the pandemic and my lack of private transportation I'll have to limit my photography to a couple of locations within walking distance for the foreseeable future. Still I am lucky for the lack of a complete lockdown and the relatively moderate course of the pandemic in Germany. I hope you and your loved ones will stay healthy and save throughout this trying times.

Excerpt from Wikipedia:
The cane toad (Rhinella marina), also known as the giant neotropical toad or marine toad, is a large, terrestrial true toad native to South and mainland Central America, but which has been introduced to various islands throughout Oceania and the Caribbean, as well as Northern Australia. It is a member of the genus Rhinella, which includes many true toad species found throughout Central and South America, but it was formerly assigned to the genus Bufo.
The cane toad is an old species. A fossil toad (specimen UCMP 41159) from the La Venta fauna of the late Miocene in Colombia is indistinguishable from modern cane toads from northern South America. It was discovered in a floodplain deposit, which suggests the R. marina habitat preferences have long been for open areas. The cane toad is a prolific breeder; females lay single-clump spawns with thousands of eggs. Its reproductive success is partly because of opportunistic feeding: it has a diet, unusual among anurans, of both dead and living matter. Adults average 10–15 cm (4–6 in) in length; the largest recorded specimen had a snout-vent length of 24 cm (9.4 in).
The cane toad has poison glands, and the tadpoles are highly toxic to most animals if ingested. Its toxic skin can kill many animals, both wild and domesticated, and cane toads are particularly dangerous to dogs. Because of its voracious appetite, the cane toad has been introduced to many regions of the Pacific and the Caribbean islands as a method of agricultural pest control. The common name of the species is derived from its use against the cane beetle (Dermolepida albohirtum), which damages sugar cane. The cane toad is now considered a pest and an invasive species in many of its introduced regions.
The American bullfrog (Lithobates catesbeianus) is a very large native frog to southern and eastern parts of the United States and Canada. This frog is an introduced species to California where it is an apex predator with a voracious appetite. Bullfrogs eat anything they can catch including other amphibians, reptiles, rodents, crayfish, birds, and even bats.
The arroyo toad (Anaxyrus californicus) is a federally endangered species that is endemic to California and Baja California (Mexico). The United States Geological Survey (USGS) has been studying this species to better understand its habitat and movement requirements.

Renjith spotted with his amazing spotting skills. Probably we're lucky to sight this in Munnar side as not seen regularly there. This is very common in Kodaikanal district, Tamil Nadu and so named after the district.
Monsoon is around the corner. But I will miss out herping for 2 straight years because of pandemic. Right now I can only look back at previous herping adventures in my archive.
The scientific species name is honorary to French professor Alain Dubois, of the Paris Museum of Natural History in France, as an expression of gratitude and appreciation for his contributions to batrachological research and guidance to the species discoverers, S. D. Biju and Franky Bossuyt, in establishing their initial research projects (Biju and Bossuyt 2006). (amphibiaweb.org/species/6730)
I was not aware of the correct pronunciation of the species name until I watched Adam Sandler's recent movie "Hubie Halloween" on Netflix where his titular character name is Hubie Dubois. He is called as 'Doob-Wah' in the movie. Until then, I was pronouncing it as "Doob-Oh-yus."

Fire-bellied toads (genus Bombina) are primitive anurans known and named for their yellow to red and black belly patterns. If threatened they will display these warning colours to potential predators by arching their backs and raising their legs and chin.
The European fire-bellied toad reaches it's northwestern range limit in the Morainic Uplands of eastern Schleswig-Holstein. While internationally of least concern, in Germany the species is listed as endangered, critically so in the northernmost federal state. From 2004 to 2009 the mainly EU funded conservation program "LIFE-Bombina" to the tune of over 2 Million € coordinated protective measures in Denmark, Sweden, Latvia and Schleswig-Holstein. Fundamental genetic research, a breeding and headstarting program, the creation of 160 new water bodies, wetland restoration, habitat optimization, coservation grazing and the creation of stepping stone habitats to reconnect the gene flow between populations have helped to stop the decline and in fact many populations have grown considerably.
I was lucky enough to visit one of the largest populations in the state with several hundred male callers during breeding season. Words can not desribe the ethereal beauty of hundreds and hundreds of bell-like chimes carried over by the wind, interweaving into an almost tangible cover of sound spread over flooded meadows. In fact, the local conservation trust gives guided "concert tours" every year as part of it's public outreach program. Maybe this nice little YouTube video can give you a very small scale impression:

Update 19.03.2020: Good news! The most recent version of the Red List for Schleswig-Holstein has upgradet Bombina bombina from "critically endangered" to "endangered". :)
A young Eyelash Viper found in the mid/upper elevations of Braulio Carrillo National Park, Costa Rica. This snake was spotted after several hours of night hiking for anurans. This color phase is sometimes referred to as the "Christmas Tree" morph due to its overall green coloration and reddish blotches.
