Ruby-throated Hummingbirds and Baltimore Orioles Are On The Way

Ruby-throated Hummingbird

The opportunity to see hummingbirds through-out their nesting season is great! Living in local urban areas such as Caledon, Bolton and Halton Hills gives you that wonderful opportunity. And we are always jealous (but thrilled to hear) of the great hummingbird stories from customers who spend time in The Kawarthas, Muskokas and Haliburton Highlands. In the GTA most of us have to be happy with a lucky glimpse in the spring (May-June) or in the fall (August-September) but based on customer sightings reported to us in since 2012 there are some summer GTA hotspots that have all summer success with hummingbirds. In 2020 nesting hotspots included:

  • Etobicoke around Centennial Park and south of The Queensway along the Etobicoke Creek green space
  • Neighbourhoods along the Toronto Lakeshore
  • Mississauga along the Credit River green space in particular around the Riverwood Conservancy and Erindale Park
  • Brampton in the Heart Lake area

Sometimes just a lucky glimpse or the jewels of summer are with you throughout the season, it is always as a thrill to see these amazing diminutive creatures. 


Baltimore Orioles

Baltimore Orioles have adapted very well to nesting in the GTA. When we first owned the store 20 years ago, Baltimore Oriole sightings were as rare as Ruby-throated Hummingbird sightings. Over the last five years migration sightings of orioles has become a regular occurrence but during this timeframe nesting sightings (we define oriole nesting sightings as a sighting that takes place mid June through July) have increased every year. The sightings are not just in specific pockets of the GTA but from many GTA neighbourhoods.

If you have tried for hummingbirds in the past with no success but you would still like a beautiful colourful migratory bird to visit your backyard you should definitely try to attract the Baltimore Oriole. 

Nectar for Hummingbirds and Orioles

  • Nectar formula – 4 parts water to 1 part white table sugar. This ratio is the closest to the chemical make-up of naturally occurring nectar
  • Boil the water and add the sugar. Boiling helps dissolve the sugar and if you are unsure of the quality of the water (possible bacteria in the water), boiling will sterilize the water and reduce the potential fermentation of the nectar (cloudy nectar). In the GTA boiling the water will also help remove much of the chlorine
  • Do not use red food dye, honey or brown sugar
  • Commercially sold fine grind white cane sugar (such as WBU Hummingbird/Oriole Nectar) is another excellent choice


Nectar Change Guideline

Temperature…...............Change nectar after

   ºC      ºF    

22-24 (71-75).................................6 days

24-27 (76-80).................................5 days

27-29 (81-85).................................4 days

29-31 (85-88).................................3 days

31-33 (89-92).................................2 days

34+ (93+)....................................change daily

Or whenever the nectar appears cloudy, often this is a sign of bacterial growth in the nectar

Cleaning your nectar feeder

  • Plastic feeders or parts - do not use soap to clean the feeder/parts. Studies have shown the plastic can absorb the taste of the plastic and the hummingbirds often avoid these feeders
  • Just rinse the feeder/parts with water, if cleaning is needed use vinegar or for serious cleaning use bleach and in each case thoroughly rinse the feeder
  • Glass/metal feeders or parts – rinse with water but if cleaning is required the use of soap, vinegar or bleach is acceptable. Rinse thoroughly
    Feeder Placement

If a hummingbird/s were visiting your hummingbird feeder last year use the same location, hummingbirds have a great memory,

  • A study conducted at University of Lethbridge in Alberta revealed
    "The birds can remember where every flower in their territory is and how long it takes to refill with nectar after they have fed. They also remember year to year where each feeder is, both at home and along a migration path."
  • Feeders should be placed in shaded areas to help slow down the fermentation of the nectar
  • The feeder should be within 10 – 15 feet of cover and a tall tree
  • Hummingbirds will perch high in the tree to check the area out, to ensure their safety and to keep an eye on the food source 
  • Cover is required close by for a quick exit if needed
  • If outdoor cats are a possibility hang the feeder 5 feet or higher with no plantings below
  • If outdoor cats are not an issue lower is OK and amongst native flowering plants can work very well
  • Hummingbird feeders attached directly to the window or hung off a window can work very well in some areas
  • In high hummingbird traffic areas try to keep multiple feeders located out of sight of each other. Hummingbirds can be very territorial and vigorously protect a prized food source. So like the old saying, "Out of sight out of mind"

We hope you will be calling us this year and exclaiming, "I saw a hummingbird…I did…I did!!
