Tree Swallow @ Humber Bay Park East, Toronto (Afternoon, early June, partly cloudy, 23°C).

Tree Swallows have helped researchers make major advances in several branches of ecology, and they are among the best-studied bird species in North America. Still, we know little about their lives during migration and winter.


Double-crested Cormorant perched beside the Grebe nest @ Humber Bay Park East, Toronto (Dusk, late August,  26°C).

For populations nesting in the Great Lakes region, it is believed that the colonization of the lakes by the non-native alewife (a small prey fish) has provided optimal feeding conditions and hence good breeding success. Double-crested cormorants eat other species of fish besides alewives and have been implicated in the decline of some sport-fish populations in the Great Lakes and other areas. Scientists are not in agreement about the exact extent of the role of cormorants in these declines, but some believe that double-crested cormorants may be a factor for some populations and in some locations.


Sweat Bee (Agapostemon virescens) @ Humber Bay Park East, Toronto (early morning, sunny)

This black and bright-green colour pattern makes Agapostemon virescens
the most easily identified bee species in Eastern Canada. While some
Agapostemon species are solitary, A. virescens lives in communal groups
with up to 20 females sharing a nest. You are most likely to spot these
bees on flowers during the morning in early summer. The Toronto area
is home to four species within the genus Agapostemon. To differentiate
female A. virescens from its ‘cousins’ in the genus, look for the black
back-half: females of the other three species in the genus are uniformly
bright green.


Red-necked Grebe @ Humber Bay Park, Toronto (Evening, late July, 2014, sunny).

No clear trend in population numbers. Susceptible to contaminants, such as organochlorines and heavy metals, that accumulate in tissues of prey species. Habitat loss for agriculture, roads, and development is also a threat. Listed as Threatened in Wisconsin. Otherwise no official status.


Trying out the new slo-mo feature. Not the prettiest of catches, but still nailed it. #puglife #pug @quitobicoke #ios8 #slo-mo #video (at Humber Bay Park East)
