Large amounts of grass grow in the tundra in the polar summer, and birds come to eat this grass and nest away from predators.
Taiga is cool forest ,with no growth in winter ,only summer season is best for all activities including nesting and feeding .
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
Both species don't eat and live off their fat reserves during the winter
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.
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.
Not really, but they might fly at you if you get too close during nesting season.
Species have changed since the stone age and the Aardvark is the only living species of the order Tubulidentata, of which other prehistoric species and genera are known. It is therefore certain that Aardvarks were around during the stone age.

Many died in communal roosts during winter nesting in areas where carbon monoxide was present. Clearing of dead trees removed nesting places. Now, bird nesting boxes have expanded by people, and bluebirds have returned to former numbers.
