Signs of summer: Ch-ch-changes

Besides the hundreds of molting geese, there are other changes going on as spring turns into summer. Some are pretty, like butterflies 'n flowers:

Flowering buckeye looks like it just woke up and hasn't done its hair yet... but it smells great.

(Check out the bonus ants on this iris:)

Some changes are not as picturesque, like this horrible sea monster pile of algae. The Lake Merritt Institute explains that as the day length increases, algae begins to proliferate in the shallow water just offshore. When it dies and rots, it smells like you would imagine a horrible sea monster pile of algae would, plus it lowers water oxygen levels, so the city removes it with a special harvester boat just like... they would remove... a horrible monster... OK, I admit it's a bad analogy. Later in the summer, an even more annoying water plant, wigeon grass, will start growing like crazy. The city evidently removes literal TONS of the stuff during July and August.


Sheltering in all that algae are hundreds of cormorant snacks in the form of tiny baby fish. Cormorants, like pelicans, just HATE getting algae on their faces before a big date, so the fish are probably pretty safe hiding in there.

Speaking of cormorants, their numbers are increasing as summer approaches. A few of them are breeding in the dead trees on the islands, and their combined grunting makes the islands sound like they're home to a flock of arboreal pigs. Later in summer I'll probably be able to get some good pictures of them as they herd fish cooperatively.
