Dear JOAN: Wanting to know if you can lose mild on a taking place.
Early just one morning, two purple-shouldered hawks have been frantically flapping in our swimming pool. Were they playing, battling, mating?
One particular started form of dragging the other through the drinking water towards one side of the pool. Imagining they had been drowning, I lifted them out with each other with the internet and left them poolside. I definitely felt 1 was dead.
About an hour later on, we were being woke up once more by the audio of a single flapping in the water and navigating to the other side of the pool, where he hopped out and disappeared in the bushes.
The other just one sat on the chair awhile, then fluttered to the bushes on his side of the pool. The “swimmer” was spotted in the bushes later in the morning, but neither 1 has been noticed considering the fact that.
What have been they up to?
Jan Eby, Saratoga
Dear JAN: They surely weren’t training backstroke.
You evidently witnessed the latter portion of an aerial struggle above territory. Purple-shouldered hawks, like numerous other animals, fiercely protect their territories, but the hawks do their combating in the air. They fly at each other, lock their talons jointly and cartwheel as a result of the sky, in some cases coming dangerously in close proximity to the floor.
In this scenario, they may possibly have finished up in the pool and continued to go at every single other. Though they also have elaborate mating rituals in the sky that entail soaring jointly and the male carrying out sky dances, it’s more ballet than fight.
Pricey JOAN: Considerably to my surprise and delight, I have a blue heron nest with a newborn in a person of my tall trees. Right before I found the newborn and nest, I uncovered a couple of broken eggs on the grass beneath.
The eggshells have been a mild blue in colour. I’m assuming a predator acquired the eggs. I’m curious what fowl could have gotten the eggs? I have only witnessed hummingbirds, crows and an occasional blue jay in my lawn.
Would you have any concept?
Lori Gregory, Pleasanton
Pricey LORI: You are a blessed duck to have a terrific blue heron nesting in your tree. They are incredible birds, but I do are inclined to say that about all birds.
The eggshells you located may not be evidence of foul perform. Herons will toss out the empty shells immediately after their chicks have hatched. They are in any other case messy nest-keepers, enabling collections of poo and even useless chicks to remain in the nest, but they chuck the shells.
If the eggs weren’t empty when they went out of the nest, it could have been since of inadequate nest servicing. The fantastic blue herons return to nesting web sites period following time, but they really don’t normally return to the identical nest. Rather, they pick one and do some mend perform and start out laying eggs. Existing nests, on the other hand, may possibly be ruined or weakened in the offseason by wind or by other animals stealing materials from them. From time to time, eggs slip by means of the holes and close up on the ground.
The herons do have nest predators, nevertheless. Turkey vultures, common ravens, American crows, pink-tailed hawks, raccoons and black bears are amongst the animals to prey upon both of those egg and chick.
