Large amounts of grass grow in the tundra in the polar summer, and birds come to eat this grass and nest away from predators.
A pregnant woman experiences nesting during approximately the fifth month of their pregnancy. This, however, is just an estimation and is not very accurate as nesting can occur before or after the fifth month. It is never certain when it will occur.
Kings and Queens swarm during mating season to establish new colonies
The presence of a fetus tail during development in certain species is significant because it reflects the evolutionary history of those species. The tail is a remnant of ancestral traits and can provide insights into the evolutionary relationships between different species.
Sharks are typically opportunistic feeders and do not have a specific feeding time; however, they are often more active during dawn and dusk, known as crepuscular feeding. This behavior allows them to take advantage of the low light conditions to hunt for prey. Additionally, some species may also feed more during the night, depending on their habitat and prey availability. Overall, feeding times can vary based on species, location, and environmental factors.
Both species don't eat and live off their fat reserves during the winter
Yes, there is a pecking order among seagulls, often determined by size, age, and aggressive behavior. Dominant individuals typically have priority access to food and nesting sites. This hierarchy can vary by species and location but generally reflects social structures within their flocks. Observing their interactions can reveal these dynamics, especially during feeding or breeding seasons.
Terns produce a variety of sounds, often characterized by sharp, high-pitched calls. Their vocalizations can include a series of harsh, raspy notes and whistles that are used for communication, especially during nesting and feeding. The specific sounds can vary between different species of terns. Overall, their calls are often described as a mix of squawks and screeches.
Niche partitioning is when two different species use the same resource without competing. For example fish feeding at different depths in a lake, or monkeys feeding at different levels in the trees. One species of spiny mouse eats insects during the day, another species feeds on the same kind of insects at night. Perhaps the fish feeding in a freshwater lake is an example of a freshwater niche.
yes, during "red tide" which is when a certain species of algae blooms.
Only in the sense that it is manufactured (produced naturally) by the mammary glands of the females of the species, during late pregnancy and whilst breast feeding their young.
A group of terns is commonly called a "knot" or a "ternery." These seabirds are known for their graceful flight and often gather in large numbers during feeding or nesting. Their social behavior can make these gatherings quite a sight along coastlines and shores.
There are many species which sequester alkaloids from plants, usually as a self-defence mechanism. Absorption of alkaloids by such species will usually render the organisms unpalatable largely because of the bitter taste that results. Certain ant, caterpillar, mite, frog, etc. species extract - and possibly metabolise - plant alkaloids to synthesise new ones or may simply secrete those absorbed during feeding on plants containing them.
