RESEARCH: Do American households have more cats or more dogs as pets?

Do American households have more cats or more dogs as pets? A recent 2022 research in America studied the types of pets in a household and whether dogs or cats were more popular as pets.

Studies show that, globally, dogs outnumber cats. The study showed that, in America, cats outnumber dogs. There are about 86.1 million cats and 79.7 million dogs in America.

Do birds hibernate?

Do birds hibernate?

Hibernation is a state when animals sleep during winter, especially where the winters are extremely cold and/or snowy. Not all animals hibernate. Animals such as bears, squirrels, bats, and hedgehogs hibernate. Some lizards and snakes hibernate.

When these animals hibernate, they will eat a lot of food and gain body weight beforehand to enable them to sleep throughout the winter. For example, squirrels can gain 50% of their body weight before hibernating.

Resettlement of Burrowing Owls in Southern California

In Southern California, urban developers built over the burrows of the local Western Burrowing Owls, destroying their habitats.

The Burrowing Owl (Athene cunicularia) is a small, long-legged bird in the Strigidae family of owls. It measures 19-28 centimetres (7-11 inches) tall, with a wingspan of 50-61 centimetres (20-24 inches). It is native to North America and South America. It prefers grasslands, rangelands, agricultural areas, deserts and other open dry areas. 

Unlike most nocturnal (night) owls, the Burrowing Owl is diurnal, active during the day. 

It nests in burrows underground that a prairie dog or a squirrel has dug into the soil. It also nests in other shallow, underground structures.

The San Diego Zoo Wildlife Alliance collaborated with the United States Fish and Wildlife Service to relocate the Burrowing Owls that had lost their homes when humans began building in the area.

RESEARCH: Pet dogs respond to verbs, nouns, and terms of endearment

Current research demonstrates that pet dogs respond to verbs, nouns, and terms of endearment. Also, pet dogs respond to a range between 15-215 words or phrases – with an average of 89 words, documents New Scientist in December 2021.

Researchers Sophie Jacques and Catherine Reeve at Dalhousie University in Canada conducted a study of dogs and an itinerary of words to determine how many words, on average, dogs respond to. Rather than defining how many words dogs ‘know’ the researchers studied how many they ‘respond to’ – which means that the dog performed a trick or obedience behaviour, or performed an action such as tail wagging, or began looking at something or a direction, or search around for an item.
