Grebe pairs have gone so far as to make their floating nest and in some cases laid up to two eggs. On EACH OCCASION, on returning a few days later the nest has been deserted and in some cases obviously taken over by a Coot pair.
Then in some cases it appeared that nests have been abandoned even with a remaining egg.
On one occasion there appeared to be a number of nests that had
been abandoned in this manner.To the point that even a duck was able to scramble over the nest - egg as well!
It seems very labour consuming to continue building nesting sites in this manner, lay egg(s) only to then abandon the project. Or is there another answer to it?
Earlier this week it was interesting to see one pair of Grebes sizing up a patch of floating weed suggesting that they might be looking for another site. Returning yesterday it was pleasing to see that the Grebes once again had made this their nesting site, were incubating another egg and were CO-existing with the neighbouring coots, a the painting below shows.
A pair of Grebes and Coots nest close by to one another, After having seen the Grebes at a number of sites like this, one is left wondering if this nest will succeed?
A second pair of Grebes were spotted sizing up an area of reed, but it was not long before they were under attack from a Coot.
The Coot attack.
It was not long before the coot was returning to maintain his claim to the territory.
One is left wondering why the Grebe does not stand up to its the rival the coot more often?
