It doesn’t matter what kind of duck, either. Interestingly even when all water sources may be frozen some individual herons may remain during the winter months surviving on small mammals. The Swan's nesting season is timed to take advantage of readily available food supplies. They will be more vulnerable to being picked off by predators such as seagulls, herons and crows – which have all been known to eat unguarded cygnets. Can it feed it-self efficiently? While you may be familiar with some of them already, the odds are that there are quite a few which you aren’t. As you know (see the section, Swan Biology) birds are warm blooded and their temperature has to remain within a very narrow band in order to remain healthy. It is nature’s way of telling the pen and cob that hatching is imminent and for all the other potential hatchlings to ‘time’ their emergence so all of them hatch on the same day.

This would lead to an increase in the mortality rate and the brood size would decrease. So, when it emerges from the egg, it adsorbs the remains of the yolk into its body. They then swallow them whole although they may give fish a good shake first to help break any potentially dangerous sharp spines. Did you know? Because they are opportunistic feeders the exact species of fish depends on what’s available in the local ecosystem. 8. In these situations, the mature swan will resist their offspring’s attempts by swivelling round when they see or feel the cygnet trying to get on board. They will be more vulnerable to being picked off by predators such as seagulls, herons and crows – which have all been known to eat unguarded cygnets.

And this goes for both in the wild and in backyard ponds and water features where they may be looking for an easy meal. While that “hair” is really made up of feathers they are nevertheless fun to look at.

Snakes are on the heron’s menu. This is a dominant reason why more baby swans die in the second week compared to the first week. Another time when cygnets rest for long periods of time on the parents’ back is at night.

This section will cover what happens to the family of swans during the first two weeks of the cygnets’ life. Normally before the first two weeks has passed, they are able to upend for a couple of seconds and increase the depth of water in which they can find sustenance.

What I have seen is that the adults, mainly the pen, will use the foot-trampling action to show ‘excitement’ or anticipation, of food to come and her action of doing this seems to draw her young closer in. One other thing that all swans do, not just the cygnets, is to expose their webbed feet to the air when they’re in the water. If you’re a bird watcher, much like myself, you probably enjoy learning new things about the birds we love to watch. For example mice and small rodents such as voles often make up a substantial part of their diet.
