Olive Sided Flycatcher, Comet 13P/Olbers July 2024 and Stuff

Olive Sided Flycatcher @ South Cameron Woodlot in Windsor ON

I have been trying to "birdwatch" in my backyard for the last few days --- and its been really good! For late August and the whole month of September - I have come to find that there are usually a few warblers in my back hedgerow behind my house. My yard list is growing! This gorgeous Olive sided Flycatcher caught my interest, mid-afternoon, when it was flycatching off a dying White Oak behind my house. It was an unmistakable ID. It was neat to see it catch bugs and then eat them while I was sitting on my back porch. 

Edit: This bug might be the famous "Giant Ichneumon Wasp" (long ovipositor)

Some neat birds seen over the last 3 days:

Monday Aug 26th:   Bobolink (new bird to yard list), Olive Sided Flycather. Least Flycatcher

Sunday Aug 25th:  Tennessee & Nashville Warblers, Least Flycatcher, Ruby throated Hummingbird

Saturday Aug 24th: Cape May Warbler, Warbling Vireos, Least Flycatcher, Baltimore Oriole

 

Female Bobolink - a new yard bird!

A while back, I had made a few attempts to photograph Comet 13P/Olbers. Using star-mapping software --- I was able to find it. You start by finding brighter nearby stars, then star-hop until you get an exposure of the comet. This photo has the comet in the center of the frame but only appears as a tiny fuzzy blur. 

Some Neat butterflies that I had seen this summer - Zabulon Skipper and Horrace's Duskywing were seen which was really nice.  These photos below are not about a month old. It was neat to see two broods for Zabulon Skippers.

Good Birding & Butterfly Watching!

European Common Blue - a chance sighting in Downtown Toronto

 

I was in New Brunswick for about a week at the end of July. While stopping in Toronto, I was at a library in downtown Toronto and a friend mentioned that I check for locations of European Common Blue butterflies. Using I-naturalist I realized there were sightings within a few kilometers from the location I was at.  I was willing to walk to other locations, but figured I would first try the field adjacent to the library (see map below) . Fort York Library is along the train tracks just a few blocks south of Union station (concrete jungle). Within a moment of inspecting the adjacent field, a bright flashy blue butterfly species was observed, and I was able to get some modest, diagnostic photos with just my cellphone. 

Much like an Azure butterfly in flight (or perhaps a blue morpho), there are blue-ish "flashes" as the male flies around. For this butterfly - its strikingly "brighter" flashes of blue than the typical Azure species. These butterflies were strongly associating with bird’s-foot trefoil.

Here is something neat about this butterfly: (It has a symbiotic relationship with ants! Note: The extirpated Karner Blue butterfly also has this trait!)

"Not always, but sometimes, something amazing happens: ants take the European Common Blue caterpillar into their nest. The ants will protect the caterpillar from predators and parasitoids and feed it ant eggs and larvae. In exchange, the caterpillars secrete (from specialized glands) a sweet liquid or honey - dew. This mutualistic relationship is called “myrmecophily,” and it occurs between specific species of ants and other organisms, especially other lycaenid butterflies. Luckily for the European Common Blue, there is a native species of ant, the Turfgrass or Labour Day Ant (Lasius neoniger), that has adapted to tend it. This ant species has also been seen to partake in myrmecophily with a native butterfly species, the Silvery Blue (Glaucopsyche lygdamus)." (ROM)
