Re: [cobirds] Common Nighthawk, Louisville, Boulder County

I've seen a pair in our Louisville neighborhood as well as above Walden Reservoir in North Park. 

I get pretty excited to see them because the Common Nighthawk isn't so common anymore, but maybe they're recovering a little?

Here's a pic I took in Walden.

This evening just before 7:30 PM I glanced out the window to check out the hummingbird feeder, but instead I noticed Common Nighthawks soaring over the cul-de-sac. There must have been at least 20 plus a Barn Swallow or two. It reminded me of the late 1990’s and the 5:00 PM hour when the nighthawks were very regular.

I was wondering if there is a list of dates and places for the fall counts available yet.

[cobirds] Lake Granby frigatebird

Hi all:

The recent report of a Magnificent Frigatebird at Lake Granby is interesting. However, the photo provided in the eBird checklist does not rule out any other species of frigatebird. One photo I've seen suggests that the bird has a white axial spur, which suggests Lesser Frigatebird (LEFR) or, even less likely, Christmas Island Frigatebird (CIFR).

There are zero records of CIFR in the ABA Area, although the great wanderings of many frigatebird species suggest that almost any species could occur almost anywhere. However, there are six previous ABA-Area records of LEFR, including Wyoming's only frigatebird record.

Given that another photo I've seen of the Lake Granby frigatebird does not show a white axial spur, the bird might not sport that feature, but none of the photos I've seen are anything close to what we might call good photos, so any specific ID one might want to paste upon the bird is suspect. It's certainly a frigatebird, but its specific identification is well beyond certainty given the photos available.

Who knows where that bird went after visiting Lake Granby, but it could be almost anywhere... including Wyoming, so keep watching the sky.

Sincerely,

Tony

Re: [cobirds] Magnificent Frigatebird

I had nothing better to do today, so I drove over to Lake Granby. No luck on the Frigatebird after 4hrs. I drove the south and west shores twice, went over to Willow Creek reservoir and to Shadow Mountain lake, but no luck. It could just be roosting in a tree. 

Cheers,

Hi Peter et al.,

Two Lesser Frigatebirds have been reported in the US this year, one in Ohio and one in California. (See https://www.aba.org/lesser-frigatebirds-in-ohio-and-california/). This species can be difficult to separate from Magnificent Frigatebird; key marks include white on the axillary feathers and sometimes a pinkish bill. Peter, is there any chance you can make the photos from Aug 1-2 available? If it's a Lesser Frigatebird it would be a first state record and the 8th for the ABA area. (One of the accepted Lesser Frigatebird records is from Wyoming.)

Anybody who chases this bird today should try to get good looks and photos to confirm which frigatebird species is involved.

All, 

Late yesterday evening, I received an email with a report of a female Magnificent Frigatebird from Rainbow Bay in Lake Granby. This report is now on eBird.  I then found a CBRC report of the same bird seen along the south shore of Lake Granby on August 1 and 2. This report has a better, but not great, photograph.  So, it looks like the bird has been there for a few days. This would be the 5th state record of this species in Colorado. 

Cheers,  Peter Gent. 

Boulder.
