The last of the active nests has been vacated. The three bluebirds that have been fed and protected by their parents for the past several weeks in the nest box at the Butterfly House, have fledged. They are out in the real world learning how to secure food for themselves, find shelter, and hopefully avoid predators.
The only activity in any of the nest boxes is that of spiders and wasps.
The paper wasp nest at the Sailboat Pond box had been removed twice, was restarted and, since last week, has had only minimal work done to it, a few more cells have been added.
The spider in the photo has been in the nest box at the Picnic Dome for at least three weeks. It looks to be a barn spider (Araneus cavaticus), but I may be wrong. I haven’t seen it in any other position other than what you see in the photo, so I haven’t nailed down the identification of the orb web weaving arachnid. It is certainly an Araneus spider if not a barn spider.
I’m not sure what this spider’s strategy is, but I could see no web nearby. Perhaps it builds a web each night and nothing remains of it in the morning when I check the nest box, difficult to say. It is, though, the only sign of life in the Picnic Dome nest box.
I do not think there will be any further nesting activity from the birds. Just to be sure, I will make one more check of the boxes next week. I’ll give a summary of the season, if I detect no further bird activity, at that time.
Till next week.
