Frog and Toad Videos

This is a list of links to all the short videos of frogs and toads that you can find on the individual frog pages. The list is in alphabetical order using the Latin names. Some videos include sound, many do not. These simple videos are intended to show how a frog or toad moves or to show it in its habitat, but some of them show interesting behavior, and many offer a look and a listen to calling frogs during the breeding season. They have been kept short, and small, and sometimes without sound, to conserve bandwidth use, which was an issue when most of these were made in the late aughts. Most of them were shot quickly at the time and place where the animal was found before it ran or crawled away. In many cases this was at night with poor artificial lighting, and in many cases the animals were uncooperative. Because many herps quickly run away and hide and others only move for a few seconds then remain motionless even when prodded, it is often hard to film herps in motion without capturing and staging them. Consequently, many of these videos use a few short segments to avoid showing only motionless frogs and toads. Click on the camera icon to watch a video. Many of these videos are in the Apple Quicktime .mov format which no longer works on all browsers, including the most popular browser Google Chrome. Be aware that Chrome might download the video to your computer for you to play offline. It is recommended that you watch these videos on Apple's Safari Browser or Firefox, which still play the .mov format as of June, 2026. Click on a link to visit the home page for a frog or toad.

*Toads - Anaxyrus* (formerly Bufo)**
	Anaxyrus boreas boreas - Boreal Toad	A toad gives a release call after he is picked up and gently grasped across the back. (It may sound like this toad is suffering, but it is not being harmed. This is a warning call, the same one he makes when another male toad comes into his territory or climbs onto his back and grabs him tightly with his legs.)
	Anaxyrus boreas boreas - Boreal Toad	An adult Boreal Toad hops around a coastal plain in Humboldt County.
	Anaxyrus boreas halophilus - California Toad	This short video shows the life cycle of the California Toad, from the late winter breeding season when frenzied males call and compete and pair up with females who lay long strings of eggs, to tiny black tadpoles just emerged from the eggs then developing and forming huge feeding masses, to the tiny toads, recently-transformed from tadpoles, massing together around the pond edge then dispersing on their own, to an adult toad moving about on its own, as it will remain until the next breeding season.
	Anaxyrus boreas halophilus - California Toad	In late winter just before the breeding season, a huge California toad is found resting underneath a piece of wood near a pond.

	Anaxyrus boreas halophilus - California Toad	A male California Toad calls during daylight from the edge of a rocky creek in Alameda County. The call does not seem to be an agressive or release call, because no other solo male toads were nearby or in contact with him, but there was an amplexing pair swimming back and forth in the water about ten feet away from him.
	Anaxyrus boreas halophilus - California Toad	These videos show some California Toad breeding behavior at the shallow outlet of a pond in Contra Costa County where at least 8 solo males and 10 pairs in amplexus were observed in the area. Not all of them are seen in the videos. Some are heard off camera.

	Hyla wrightorum - Arizona Treefrog	A calling male is swarmed by a bunch of other frogs (presumably males) who begin attempting to amplex each other, resulting in encounter and release calls. It could be that a female had entered the territory and that attracted them. If so, she managed to escape without being grabbed one of the males.
	Hyla wrightorum - Arizona Treefrog	Several views of males and females in amplexus, with examples of other frogs approaching them and jumping over and around them (reminding me of the old children's game of Leap Frog.)

	Hyla wrightorum - Arizona Treefrog	Male frogs compete in the breeding pool at night, swimming and jumping all over each other in a frenzy.
Bullfrogs - Lithobates
	Lithobates catesbeianus - American Bullfrog	A big male bullfrog calls from the edge of a lake in the daytime. He sat making single calls every few minutes, until suddenly lots of other bullfrogs began calling all around him and then he made longer series of calls. Here we see him start with a full series of calls, then wait a bit before making a second series of calls, but this time starting with some longer notes before doing his typical calls. There was a second male about 10 feet from him who was silent, but after this male makes his second full series of calls, the second male begins calling at 1 minute 10 seconds into the video. We can't see him, but he is about as loud as the first frog. You hear him when you can see that the first frog is silent. The second male's calling disturbed this frog so much, he made a short, sharp, territorial call and leaped in the air in the direction of the second frog. He landed closer to the second frog, but the second frog hadn't moved.
	Lithobates catesbeianus - American Bullfrog	This is a very short version of the first series of calls heard in the long video above.
	Lithobates catesbeianus - American Bullfrog	This is also from the long video above - the short, sharp, territorial call made just before the frog leaps toward the other male.
	Lithobates catesbeianus - American Bullfrog	Views of several bullfrogs in ponds and creeks.
	Lithobates catesbeianus - American Bullfrog	A large male Bullfrog calls at night from a lake.

	Lithobates catesbeianus - American Bullfrog	Bullfrogs sitting around a crowded pond interact with each other, making chirping sounds and other noises.
	Lithobates catesbeianus - American Bullfrog	Hundreds of bullfrogs make their frightened chirping sounds as they jump in and out of the water, or run across the surface to escape from danger.
	Lithobates catesbeianus - American Bullfrog	Although they are quick to swim to the bottom when first approached, American Bullfrog tadpoles will usually calm down and resuface, where they slowly swim, float, and socialize.

Leopard Frogs - Lithobates
	Lithobates berlandieri - Rio Grande Leopard Frog	A male Rio Grande Leopard Frog calls at night from the edge of an agricultural canal in Imperial County, using his throat sack as well as pouches on the side of the neck to produce a variety of sounds. Another leopard frog joins in and they are both accompanied by an American Bullfrog.

	On a sunny August day in Santa Cruz County Arizona, I watched a bunch of Chiricahua Leopard Frogs go about their business around a nearly evaporated cattle pond. The next day a huge thunderstorm hammered the area, filling the ponds back up, but I was lucky to film the frogs when their foraging grounds were limited. After initially fleeing from me, they eventually tolerated my presence and crept back onto the shore, sometimes only several feet from where I was standing, and began feeding. Below are five short videos of these frogs in and around the pond. I estimated there were almost 60 frogs.
	Lithobates chiricahuensis - Chiricahua Leopard Frog	After first fleeing me by jumping into the water, the frogs gradually hopped out of the pond and sat and waited to try to catch some of the many flying insects and invertebrates that landed on the mud around the pond.
	Lithobates chiricahuensis - Chiricahua Leopard Frog	As the temperature increased, the frogs began to assemble into groups, including some large piles of over a dozen. I could not figure out the reason for this behavior, but it appeared to be some kind of social interaction, since they were not feeding.
	Lithobates chiricahuensis - Chiricahua Leopard Frog	The frogs mostly sat and waited for food, but occasionally they crawled or hopped quickly to catch an insect. They jump so quickly to catch their food, that it is almost not visible in real time. This video shows a number of frogs feeding in real time, then repeated at the end in slow motion where you can see their huge mouths and tongues in action.
	Lithobates chiricahuensis - Chiricahua Leopard Frog	Not every feeding attempt was successful. In the first segment you see a frog leap after a worm, then spit it out along with some apparently distasteful red ants. The frog had to use its front feet to pull the ants off of its tongue. The ants continued on afterwards a little shaken, but apparently unharmed. The next segment shows a large flying insect crawling on the shore, with several frogs leaping one by one towards it only to decide it was not edible.
	Lithobates chiricahuensis - Chiricahua Leopard Frog	A Chiricahua Leopard Frogs sheds its old skin, using all four legs to pull the skin and push it towards its mouth which is opened and closed to help pull the skin off. Here you can see the skin pulled from the front toes and rear legs. This one minute video was cut down from about four minutes, but the shedding went on for much longer.

	Lithobates chiricahuensis - Chiricahua Leopard Frog	Views of a different group of Leopard frogs from those above at a different pond covered with red vegetation, as they hop around, bask, feed, and shed.
	Lithobates pipiens - Northern Leopard Frog	An adult male calls during daylight from a marsh in Manitoba, Canada in May. Other Northern Leopard Frogs, Boreal Chorus Frogs, and Canadian Toads are heard in the background along with several birds.
	Lithobates pipiens - Northern Leopard Frog	Two videos of a Northern Leopard Frog calling on a sunny April afternoon in Grant County, Washington. Redwinged and yellow-headed blackbirds and other birds are heard in the background. Calling was sporadic over a long period of time, so these calls have been assembled from longer videos.

	Incilius alvarius - Sonoran Desert Toad	Sonoran Desert Toads in a rain pool at night in Arizona, including an interaction between two toads where one makes a release call. Lowland Burrowing Treefrogs and Couch's Spadefoots are calling loudly in the background, which might be why these weak-voiced toads were not calling, only waiting around on the banks and in the water for females to come.
Treefrogs (Chorus Frogs) - Pseudacris
	Pseudacris cadaverina - California Treefrog	A male treefrog calling on a windy night from the edge of a small pond in San Diego County. He makes three distinct sounds - a low call, then several higher-pitched calls followed by some ratcheting notes, ending with another high-pitched call.
	Pseudacris cadaverina - California Treefrog	At night at a small pond in San Diego County, after I make an imitation of his call, a male frog repeatedly makes what appears to be his encounter call while aggressively moving towards the camera until he finally hops away. A Red-spotted Toad and other CA Treefrogs are heard in the background.
	Pseudacris cadaverina - California Treefrog	A male treefrog calls from the edge of a small pond.
	Pseudacris cadaverina - California Treefrog	California Treefrog tadpoles in a shallow sunny pool in a slow-moving creek flowing through a San Diego County desert canyon.
	Pseudacris hypochondriaca hypochondriaca - Baja California Treefrog	A male Baja California Treefrog calls at night as part of a chorus of frogs in Kern County. He starts with the two-parted call, then speeds up a bit slurring the two parts together into what is almost a one-part call which he then alternates with the two-parted call.

	Pseudacris regilla - Northern Pacific Treefrog	In this short video you can hear some land calls and see a couple of loations in Washington where the land calls are being made. (And you get an idea of how hard it is to find a land-calling frog in such dense vegetation.)
	Pseudacris sierra - Sierran Treefrog	Three adult male Sierran Treefrogs make their advertisement call one afternoon in early March in Contra Costa County.
	Pseudacris sierra - Sierran Treefrog	Three adult male Sierran Treefrogs make their encounter call. These calls were elicited by making a raspy noise near the frogs as they were sitting on the water in calling position. The call of each frog is slightly different.
	Pseudacris sierra - Sierran Treefrog	A male Sierran Treefrog makes a few advertisement calls, until a second frog between him and the camera, makes a raspy trilled encounter call. The first frog responds with his encounter call, but when the second frog continues, he then turns to face his aggressor and charges toward him, continuing to make his encounter call. The second frog changes his call to a faster one part call. Finally they both stop, and the first frog sucks in his throat sac and dives underwater.
	Pseudacris sierra - Sierran Treefrog	An adult male Sierran Treefrog makes a one-part call while floating on the water on a sunny afternoon in Contra Costa County.
	Pseudacris sierra - Sierran Treefrog	The camera zooms out from a calling Sierran Treefrog to show an overview of his habitat in Contra Costa County.

	Rana draytonii - California Red-legged Frog	A large adult California Red-legged Frog sits still at the edge of a pond under some vegetation until a grasshopper lands nearby when it explodes into action, grabbing the insect on the underside of its long sticky pink tongue.
	Rana draytonii - California Red-legged Frog	The same frog seen above eating grasshoppers, but this time in slow motion so you can see the big pink tongue in action.
	Rana draytonii - California Red-legged Frog	Red-legged frogs around a couple of small ponds in July.
	Rana draytonii - California Red-legged Frog	Red-legged frogs around a small pond in August.
	Rana draytonii - California Red-legged Frog	Two male California Red-legged Frogs are seen here in a Contra Costa County pond in March in amplexus with California Toads (possibly female.) Male toads attempt to wrestle the frogs off their prospective mates. When they grab the frogs, the frogs give their low chuckling release call, while the toads make their peeping release call. The video also starts and ends with the frog release calls.
	Rana draytonii - California Red-legged Frog	More shots of male California Red-legged frogs in amplexus with California Toads.
	Rana draytonii - California Red-legged Frog	Lots of recently-metamorphosed California Red-legged Frogs jumping from the shore into a small drying-up Contra Costa County pond in early September.

	Rana draytonii - California Red-legged Frog	A brief look at two masses of fresh red-legged frog eggs in a small pond.
	Rana draytonii - California Red-legged Frog	Quick looks at a few large California red-legged frog tadpoles in a couple of small ponds. It's hard to get good pictures of these tadpoles because I'm not allowed to catch them. The one shown clearly was actually injured and dying floating at the edge of a pond, so I was able to get it in focus, at least.
	Rana draytonii - California Red-legged Frog	This video shows breeding habitat on a sunny day in late January with several male frogs calling along with some birds singing. You'll probably have to turn the volume all the way up to hear the frogs, but you won't see them. I've tried to photograph frogs calling but without any luck. It appears that at this location they call from locations hidden within the reeds, so this is the best I'll ever do here.
Yellow-legged Frog - Rana
	Rana boylii - Foothill Yellow-legged Frog	A Foothill Yellow-legged frog calls at the edge of a small pool in a river with just its head out of the water, producing a call that can be heard in the air and underwater. The sounds heard here were recorded with an underwater microphone placed about 3 feet behind the frog.
	Rana boylii - Foothill Yellow-legged Frog	Scenes from a Foothill Yellow-legged Frog breeding site along a river in Oregon, including calls made in the air and underwater. (The underwater calls were not recorded along with the video, they were added later, however, the frogs depicted underwater are calling male frogs.)
	Rana boylii - Foothill Yellow-legged Frog	Foothill Yellow-legged frogs trying to hide by blending in with the rocks on the bottoms of several creeks in California and southern Oregon.
	Rana boylii - Foothill Yellow-legged Frog	Tadpoles feeding in a rocky creek in Douglas County, Oregon.
	Rana muscosa - Southern Mountain Yellow-legged Frog	Some of the few last remaining juvenile and adult Southern Mountain Yellow-legged Frogs hang on in a small creek on a sunny summer day in the San Gabriel Mountains.
	Rana sierrae - Sierra Nevada Yellow-legged Frog	These are five videos of three different male frogs calling during an early summer afternoon in Alpine County. Running water, birds, insects, and an occasional Pacific Treefrog are heard in the background.
	Rana sierrae - Sierra Nevada Yellow-legged Frog	Several pairs of male and female frogs in amplexus are seen in this video with attempts by other males to steal the females. They are successfully fought off by the amplexing males, usually by a strong kick, but sometimes a long wrestling match ensues.
	Rana sierrae - Sierra Nevada Yellow-legged Frog	Several groups of male frogs are seen during the breeding season chasing and amplexing each other. You can hear release calls in the first few scenes. This behavior continued for hours, so it did not appear that they were mistaking each other for females they could breed with, but that it was some kind of territorial behavior between males. Or they could have been practicing their pouncing skills for when they encountered females in the future. (This is a long video which might take some time to download.)

	Rana cascadae - Cascades Frog	A male frog discovers another frog (probably a female that has already laid eggs) grabs on to her, and is carried around the pond as she tries to shake him off.
	Rana cascadae - Cascades Frog	This was recorded under the water of a small snow-melt pond at about 7,145 ft. elevation (2178 m) in July in Siskiyou County. © Risa Okuyama. We hear the underwater calls of a male Cascades Frog and see a male in amplexus with a female as she lays her eggs. You can see her small dark eggs coming out before they expand from exposure to the water into a large egg mass like the one we see in front of her. Then another male swims onto the amplexing male's back and tries to knock him off the female, but he holds on.

Burrowing Treefrogs - Smilisca
	Smilisca (Pternohyla) fodiens - Lowland Burrowing Treefrog	Two males call at night while sitting on wet grass at the edge of a shallow rain pool in Pima County, Arizona.
	Smilisca (Pternohyla) fodiens - Lowland Burrowing Treefrog	Males at night, calling and waiting from dry land next to a breeding pool in Pima County, Arizona. Couch's Spadefoots can be heard calling in the background.
	Smilisca (Pternohyla) fodiens - Lowland Burrowing Treefrog	Sitting at night in the Arizona desert next to a breeding pond where other Lowland Burrowing Treefrogs and Couch's Spadefoots are calling, a frog repeatedly snaps up bugs with its big pink tongue, which you can seen when the action is slowed down a few times.
Spadefoots - Scaphiopus and Spea

	Spea hammondii - Western Spadefoot	A tiny juvenile spadefoot, which probably transformed about 2 - 3 months earlier, is found crossing a road at night in San Joaquin County. Disturbed by our lights, it started digging into the ground in typical spadefoot fashion - using the hind legs to dig and slowly sinking down backwards to hide. But it could not dig deep enough due to the hard ground, so it hopped away into the dry grass.
	Spea hammondii - Western Spadefoot	Western Spadefoot tadpoles swim and feed in a murky rain puddle in Alameda County. The have to eat as much as possible so they will grow large enough to transform into terrestrial spadefoots before the puddle completely dries up.
	Spea hammondii - Western Spadefoot	A male and a female spadefoot in amplexus underwater in a breeding area of a rocky creek bed in San Joaquin County. You can also see some eggs by the pair and floating nearby. (The first shot is of the female after the male left her.)

	Spea intermontana - Great Basin Spadefoot	One night while searching for spadefoot choruses to record, we discovered a spadefoot crossing a gravel road. After we picked it up and moved it to the sand for photographs, it began to slowly bury itself. It took about 5 minutes to completely bury itself, but that has been cut down to about a minute here.

	Spea multiplicata - New Mexico Spadefoot	A spadefoot calls at night while floating on top of a flooded pool in a wash in Hidalgo County, New Mexico. When another male comes close he makes a different snoring sound and swims around. Other spadefoots and Western Green Toads are heard in the background.
	Spea bombifrons or Spea multiplicata	Spadefoot tadpoles in a rain pool in Cochise County, Arizona metamorphose into tiny tailed spadefoots and move onto land as the pool quickly drys up. (Shown over a period of about one week.)
	Spea bombifrons or Spea multiplicata	A tiny recently-metamorphosed spadefoot which has not yet absorbed its tail hops around next to its dessicating breeding pool with a predator attached to its tail (probably a water scavenger beetle larva.) Cochise County, Arizona. These were tentatively identified as Spea bombifrons, but there is a chance they could also be Spea multiplicata (stagnalis.)
