Fifth Try Unsuccessful for Blue Birds

Hi,
Today marks my fifth attempt to see a Mountain Bluebird at the Nanaimo river estuary. I have scoured the entire estuary several times with no positive results since the beginning of April. There have been multiple sightings reported on the rare bird alert for Nanaimo but still nothing to be seen on each of my outings.

Lots of White Crowned (pictured to the right), and Savannah Sparrows in their mating colors singing everywhere. Some Common Mergansers in the river and a huge flock of what appeared to be Greater White Fronted Geese. Although I could not get close enough to them for a good ID they had a strange whistling call almost like a wood duck. Not the loud raucous honk of the Canada Geese. They also had the tell tale grey color and the prominent black and white rings on their tails.
