Weather sure has taken a turn. Thunderstorms build over the mountains by every afternoon & highs have been flirting with 100° for 4 days now. Unfortunately, wildfire season has arrived. Bird activity has slowed, significantly, during heat of the day. Only needing to fill the black-oil seeds once a day, as zero activity after around noon, until the evening cool-down.
Seeing a change in hummingbird migration, too. Haven’t observed an adult male Rufous since Thu. Now, female & a few juvenile Rufous Hummingbirds are coming through. Same with the Black-chinneds, more females & juveniles appearing. Though, still have adult male BC coming in.
Also, with the heat extremes, cleaning the nectar feeder every 24 hrs. The other day, let it go to 48 hrs & the little nectar remaining already had hint of an “alcohol” smell to it.
