  • This is a Pteromys volans orii Japanese dwarf flying squirrel male perched at the top entrance to a nest. On this day, he was guarding a female inside the nest. She was in estrus, and the male was warding off other males. This pair mated several times throughout the day, but the female also mated with another male while this one was unaware. This photo is third in a series of three which illustrate the height of the nest.

  • This is a Japanese dwarf flying squirrel (Pteromys volans orii) flying through the forest on a cold winter day. Usually nocturnal, these animals sometimes become active in the day during reproductive season.

  • This is a male Pteromys volans orii flying squirrel gliding through the canopy in mid-afternoon. This species is primarily nocturnal. During the peak of the reproductive season, they can become active during the day when there is competition among males for a female in estrus, as was the case here.

  • Competition between rival males for the right to mate with a female flying squirrel (Pteromys volans orii) in estrus can become heated. The two males pictured here chased one another up and down the tree, culminating in one executing a full body-slam punch, sending the other into the air.

  • During reproductive season, Pteromys volans orii flying squirrel males sometimes compete for females that have gone into estrus. Pictured here are two male rivals. One is guarding the entrance to a hole in a tree. Inside is the female. The other male is sneaking up from the other side of the tree with the intention of challenging the ensconced male.

  • This sequence of 17 images shows a humpback whale (Megaptera novaeangliae australis) executing a forward breach. As the whale emerges from the ocean, water streams off the animal’s body, as well as from the sides of the whale’s mouth. The whale exhales with great force as it surfaces, creating a cloud of water vapor, then inhales through open nostrils before plunging back into the water. The entire sequence spans just over one second of time. Image 3 of 17.

  • This is a male Eden’s whale (Balaenoptera edeni edeni) known as Mesa, demonstrating the Drawbridge technique for feeding on anchovies. The whale raises his head above water to approximately eye level, then drops his lower jaw rapidly as if lowering a drawbridge. He then maintains a stationary, mouth-open position for an extended period of time, sometimes up to 30 seconds, during which time anchovies jump into his mouth. When he collects sufficient fish, he closes his mouth and reenters the water. Mesa is part of an isolated population of Eden’s whales, which are a neritic member of the Bryde’s whale complex, that live in the shallow waters of the Gulf of Thailand. It is likely that there are 50 or less in the population. Photo 7 in sequence of 7 photos illustrating beginning of Drawbridge technique.

  • During summer months, bowhead whales (Balaena mysticetus) like the one pictured here often visit shallow water, which provides a shelter from potential predation by orcas.

  • This is a young Eden’s whale (Balaenoptera edeni edeni) in the Gulf of Thailand side-lunging through a mass of fish, likely Sardinella sp., that this whale and its mother had aggregated by swimming in a large circle. This circle and side-lunge technique has become the dominant foraging technique since 2017, replacing the open-mouth trap feeding strategy that had been prevalent since the 1990s. I believe this reflects a change of target prey. The whales adapt their foraging strategies to target species.
