Slow Growth

This summer has been unusually cold with the temperature dropping as low as 7 degrees celcius at night, so growth has been slow. As a layman, I have noticed a dramatic decline in the butterfly and bee population. The number of white admirals, pink ladies and monarch butterflies seems to have decreased from previous summers. I’m not certain if this is due to dwindling habitat, change in weather patterns or other factors.

It is of note that the Monarch butterfly (Danaus plexippus) is on the species at risk list of Ontario. For more information please see

The Ruby Throated hummingbirds however, appear to continue their migratory patterns and we have the usual two to three pairs fighting over the hummingbird feeder. They also enjoy the nectar of the various garden flowers, especially the foxglove and lilies.

Both the males and females like to perch on the “weather” stick which is placed a few feet below the feeder. From there they keep a watchful eye on whoever invades their “space” and then an air battle ensues. It is an amazing show to watch as they navigate feeding and dodging each airborne assault.

The pencil sketches are a result of happy observations of these amazing and at times ferocious little birds.
