Where are the Orioles? Jefferson Co

[David Gulbenkian]

Haven't seen an oriole this year.  None in the Wheatridge Greenbelt.

Why not?

We’ve had both Orchard and Bullocks in Cherry Creek State Park in the last few weeks.

Hi all

Up north a banner year, in my yard I had, at one time, 7 Bullock's (5m, 2f), down the road at "Nunn's Gravel Pit" had Baltimore and Orchard (multiple) Oriole. A female Bullock's continues to come to yard almost daily. Others in NOCO report the same, one woman had 11 in her yard at once!

Thanks, Gary Lefko, Nunn

We saw one or two at Boyd Lake in Loveland at the end of May.

Had lots of Bullock's along the Platte River Trail in Arapahoe and Denver Counties in May, but they seem to be thinning out now.

We are seeing what I think is a decent number of Bullock's Orioles on the north shore of Standley Lake. I'm aware of at least 4 pairs - 2 just west of the visitor center, one north of the boat lauch area, and one down here by Loon Lake. This is the first year I've put out an orange / jelly feeder and I have a female that comes 3-5 times a day now! We live just a few houses south of Loon Lake. She just starting coming on Tuesday of this week.

I have started to see a huge decrease of Orioles in my neighborhood in Green Mountain. Populations started to decrease with the increase of Coopers Hawk along the front range.  Ten years ago, we had large numbers of Grackles, good numbers of Orioles, and more Robins in the neighborhood.  The decrease in my opinion was caused by the spread of Eurasian Collared Doves throughout the country.  Once they arrived, the Coopers Hawks soon followed with the large increase of food.  It used to be rare to have a Coopers Hawk in the summer.  During the winter months, it was Sharp-shinned hawks, which seemed to decrease also. The only increase has been the number of Black-chinned and Broad-tailed Hummingbirds.  They are benefiting from the decreased number of predators like Blue Jays, Grackles, etc. who prey on their nest.  Just my opinion...

I had a banner year in early to mid May with up to 7 Bullocks coming to my feeders. Since they left I have seen few around the Canon City area.  I'm afraid the continuing drought conditions has caused a number of migratory to head to other locations where there actually have insects.

That's interesting!

I'm up in Larimer, so I'm not sure how much this will apply or be helpful to you, but Bullock's Orioles nest in my neighborhood in Timnath and are relatively "frequent at this time of year."

I haven't seen but one Orchard Oriole, which was a migrant that passed through my neighborhood in May.

The Bullock's Orioles nest in deciduous trees that line one of the smaller roads in the neighborhood. They did last year, and they returned again. I'm not sure if they'll become permanent breeders in the area, but that would be a welcome treat!

The birds are happy, and so am I

Saw or heard at least three pairs of Bullocks this morning going north on the Teller Lakes Trail from Valmont Rd. in Boulder County. Also saw a very loud and prominent young Orchard Oriole along the same route. Not the same one I saw a couple weeks ago, as those were more mature. This had the coloration of a 1st year male.

I've generally been seeing more Bullocks this year than the last couple years. Could be my paying more attention or could be a trend.

Sounds like you should take a trip north to see them.

Good birding!

Hi, 

I have seen Bullock's Orioles each time I go to Bluff Lake Nature Centre - Denver County. 

Good Luck!

Just saw 8 Bullock's Oriole's this morning along the 1 mile or so stretch of the Highline Canal Trail that parallels the south shore of McLlellan Res. in SW Denver. I'm curious if the people who've birded a long time have seen shifts in where the Bullock's nest, in addition to other variations in their populations. I'll have to do some digging in the eBird records year to year to see other patterns. Interesting to focus in on this one bird while out walking.

For the first time I have Bullock’s Orioles in my yard in Aurora.  I’ve been seeing 3-4 regularly the past few weeks.   They come to the Suet feeder and are even eating sunflower hearts.  They have plenty of insects available.  They do a great job of intimidating the flocks of young starlings and blackbirds from the suet feeders and water fountains.   The nesting flickers don’t mind sharing suet with them and seem to feed more when they are there.    The flickers have been great at defending the nest boxes from all of the starlings, thanks to help from the orioles. 

I thought they were nesting in Horseshoe Park, with the zillions of Red-winged Blackbirds and Common Grackles, but one pair is nesting in a nearby Cottonwood Tree and I found another nest a few blocks away in a very large Maple.   My best guess is they are trying to nest further away from the blackbirds/grackles.

Pella Crossing and Walden/Sawhill (Boulder County) have what seems to be the regular number of orioles, though I haven’t seen this year’s nests yet.

I go out to Sawhill-Walden Ponds regularly and it seems like there are the usual numbers of Bullock's orioles singing/nesting.  I'll check tomorrow.
