Frog hugs or frog thugs?

An aggressive water ballet between two bullfrogs earlier this month at the neighbor's pond sent me to the internet to find some information on this behavior. I wondered, "was it a mating display I observed, a territorial dispute, or some form of frog hugging?,".  A search of bullfrog wrestling turned up several videos and some websites. 

One video at www.youtube.com/watch?v=si1A9jk-5BQ depicted a battle similar to the one I had witnessed. However in my humble opinion, the battle I watched was a little more epic. Nonetheless, in the video I loved the fact that at the end of the skirmish, a duck nonchalantly swims by like, "Fight's over. Nothing to see here, folks."

Other websites shed light on the display as a territorial dispute. 
​
"Behaviorally, males can be territorial and aggressive. They can sometimes be seen wrestling other males," said a post on the Berkshire Museum's website .

The frogs "settle in big enduring water bodies, like ponds, swamps and lakes. At the time of breeding, the male frog fiercely protects his territory. The call of the male is evocative of the roar like a bull, hence the name bull frog," said a post on www.learnaboutnature.com.​

I had posted a short video of the end the bullfrogs' display on the PA Herps: Pennsylvania Amphibians & Reptiles Facebook page asking for clarification. One comment on the video was "I don't know, but interesting." Another was a veiled reference to the "Highlander" movie saying, "There can be only one."

After the fight was over, the two frogs separated, but not that far away from each other. 

I searched for a little more information on bullfrogs. The PA Fish and Boat Commission had lots of great details about bullfrogs and other amphibians on their website. 

The bullfrog is "a solitary creature, more so than any of our other frogs, and does not engage in chorus singing even during the breeding season," said a post on the site.

"The bullfrog normally does not sing in chorus with other bullfrogs. Given its solitary habit, it is a lone singer, although with several individuals residing on the same water it may seem as if they were conversing with one another," the post continued.

The Berkshire Museum's site went on to describe the frog's diet.
​
​" As tadpoles, bullfrogs are herbivores who eat aquatic plants.  As adults, bullfrogs are carnivorous ambush predators who eat mice, fish, birds, snakes, baby turtles, insects and anything that will fit in their wide mouths, even other bullfrogs or tadpoles," it continued.

However despite being a dominate pond predator, "the legs of the bullfrog are considered a culinary delight by many people. In Pennsylvania, this amphibian is regulated by seasons and bag limits," said the post on the fish and boat commission's site.

​Apparently, I needed to get Sadie a fishing license. 

Other frogs that I spotted at the neighbor's pond were most likely northern green frogs. 
​
​"This abundant frog is primarily nocturnal. That is, it is most active at night, but moves about and forages a bit during the day as well. Along with the bullfrog, it is more aquatic than many frogs. It is a medium-sized frog, slightly smaller, but otherwise similar in appearance to the bullfrog," said a post on the PA Fish and Boat Commission's website. 

The nocturnal part of this statement intrigued me as I recalled several pictures of glowing frog eyes that appeared on the trail camera's night vision photos. 

I feared I often might have confused the green frog with bullfrogs at the pond. 
​
The boat commission's post provided further identification tips by saying, "The green frog appears in an assortment of colors and patterns. It may be a brilliant metallic green, or vary from greenish brown, or brownish to tan. Dark-brown or gray spots, some large enough to be called blotches, appear on the back, frequently in large numbers. The head and upper lip are green, which is especially noticeable in the adult male. A yellowish band runs along the jaw to the shoulders."

Whether it was a green or a bull, frogs were always a favorite photo subject. Mostly they were just floating, not fighting. 

Several tadpoles that were transitioning to frogs were seen as the summer progressed. Back feet developed first, then the front and then slowly the tadpole tail disappeared. 

Originally this post was just going to be random frog photos, before the whole feisty frog incident. I had searched the internet for inspirational frog quotes and only found a few. 

“Everybody loves listening to frog calls.” - Charles Carlson.

“A frog in the mud is happier than a man because he has no ambition to reach the stars!” - Mehmet Murat Ildan.

This quote was a little more perplexing to me and not so much inspirational. It kind of sounded to me like, don't try to be more than you are. I disagreed with that thought and also with the saying that frogs in mud were happy.

The frogs I have witnessed tended to be spotted in clearer water.

​However, they were buried in mud during the cold winter during hibernation. 

“Nights can never be real and enjoyable without the croaking of frogs and the chirping of crickets.” ― Michael Bassey Johnson, Song of a Nature Lover

“An old silent pond...; A frog jumps into the pond, splash! Silence again.” ― Matsuo Bashō.

​I particularly liked this phrase as it reminded me of many mornings at the neighbor's pond.

 “Eat a live frog first thing in the morning and nothing worse will happen to you the rest of the day.” - Mark Twain.

I could say was, "Eww, no thanks. I'll have the bad day".

​This must have been Sadie's mantra for her frog hunting, but still...

Floating frogs were always a nice capture. However, fighting frogs proved to be a little more interesting.

It was amazing to me that in all the years that we have visited the pond, this seemed to be the first time I had ever seen a frog frenzy like that. It just goes to show that nature is full of surprises and we've not seen everything yet even though we think we have.

​That's just the nature of things 'round here.
