Birds are an incredibly diverse animal group. This is reflected in many aspects of their reproductive ecology, as you can see in this short list of facts about the nests of birds. Largest tree nest: a Bald Eagle nest in Florida which was 20 feet (6.1m) deep, 9.5 feet...
Have you ever noticed that the level of singing activity by birds changes during the day? Bird singing varies throughout the day and generally follows a circadian (daily) rhythm, usually along what’s known as a bimodal pattern, i.e. two main periods of singing...
Birds are an incredibly diverse animal group. This is certainly reflected in their flying abilities, as you can see in this short list of facts about bird flight. Fastest bird: Peregrine Falcon diving at 117 mph (188 km/h). It is believed this bird may even reach...
Birds are very well adapted to aquatic environments, as you can see in this short list of facts about the swimming ability of birds. Most aquatic bird: the Penguins, who spend 75% of their life-span out in the open sea. Fastest underwater swimming bird: the Gentoo...
Birds are an incredibly diverse animal group. This is reflected in their physiology, as you can see in this short list of facts about the stamina and endurance ability of birds. Coldest average temperature regularly endured by a bird: -50º F (-45.6º C) by Emperor...
Bird banding recoveries permit biologists to determine how long each bird has survived in the wild. While biologists and scientists are more interested in the average life span of a species, it is also interesting to see how long it is possible for birds to live. And...
Birds are an incredibly diverse animal group. This is reflected in every aspect of their anatomy, as you can see in this short list of facts about the bodies of birds. Size Tallest bird – Ostrich at 9 ft (2.7 m) Smallest bird – Bee Hummingbird at 2.24...
Birds are an incredibly diverse animal group. This is reflected in the large differences between some of the species with regards to their breeding biology, as you can see in this short list of facts about bird eggs. Largest egg — laid by the Ostrich, it...
It’s cold outside. Much of North America is in the midst of a deep freeze with the kind of cold that makes you wish you could hide under a large pile of warm blankets. But what do birds do when it gets this cold? Pull out a small pile of warm blankets to hide...
Long, trailing Vee’s of flying ducks and geese are one of the truly enduring images of wild animals. The sight of those wavering V’s crossing the sky means only one of two things: either spring has begun or winter is close at hand. In either case, there is...
The boreal forest in North America is a vast tract of coniferous and mixed coniferous-deciduous forest which stretches from the Atlantic Ocean to the Pacific Ocean across northern Canada and through Alaska. The Canadian portion alone is approximately 2 million square...
One of the interesting types of data that scientists obtain through bird banding is information on the life span of many bird species. By re-trapping birds or receiving band reports from birdwatchers who find dead birds, scientists can use the database maintained by...
