Rather cold this morning at 9:00 – 29 degrees. But the Eagles were flying. The fish were active and other predators were around. Namely hawks. It was snowing lightly, but the activity along the Boise River was good. There was a report that there were several Eagles and yearlings further downstream from where I was. Robin was waiting in the car, hungry and cold. Best not follow up on that observation. I saw 2 adults and two yearlings, but only got to photograph the adults. Here’s what I saw. Keep Looking up!

Last night at about 7:20pm, our neighbor Becca called and said that she was out in her backyard, went inside for something and returned to her back yard. She said that “…this bird” was where she was working and that it had not been there before. She brought it to me.
I believe it is a Coopers Hawk. We have had one, or several, in the neighborhood for several years now. I hope this is not one of them. There are no visible trauma marks on the hawk and no signs of anything broken. Here are some post-mortem photos of the hawk. Left-Click to see a larger view. If someone from the Idaho Fish and Game, The Peregrine Fund or The Idaho Bird Observatory would like to have it or examine it, I will keep it for a short time. Please contact me.
The Boise Falcons seem to be doing well this cool and rainy morning. Not a heavy rain – just light showers. Both parents look good as do the eggs. I have had several comments thanking the Peregrine Fund and Fiberpipe for allowing us to see the falcons “live” through the use of the FalconCam. It is greatly appreciated. Here are some screen shots – Used By Permission: The Peregrine Fund, Idaho Department of Fish and Game and Fiberpipe Data Centers – of the action today. I may add more throughout the day. Please rate these articles as you look at them. Thanks and enjoy! Keep Looking Up!
This beautiful juvenile Cooper’s Hawk was having dinner in the alley beside our house this evening. At about 5:30pm our neighbor called and said she saw the hawk take the pigeon and now her was on the ground eating. I grabbed my camera and these photos document what I found. Enjoy! And just to let you know, I have received no reports about the whereabouts of the Boise peregrine falcons. No news is good news. Left-Click any of these photos to see them enlarged.
The Boise Falcons have been very attentive towards their four eggs. The weather here in Boise has warmed up and the temperatures under clear skies are forecasted to be in the low to mid 70’s. The falcons will like the slightly warmer and dry weather. I received this information from the Peregrine Fund this morning about the eggs and incubation.
With the arrival of egg #4 on April 2, incubation is in full swing. The incubation period is 33-35 days. With a body temperature of 104 degrees F, the adults are able to keep the eggs warm even in cold spring weather. During incubation, a “brood patch” develops on the chests of the adults. This bare spot keeps the eggs in close contact with the parents’ bodies for maximum heat.
The patch remains for up to two weeks after the eggs hatch because new chicks are unable to regulate their own body temperatures for that long and continue to depend on their parents for warmth. The brood patch fades and feathers fill back in as the youngsters grow older.
I did get out on the Greenbelt today and found the Osprey nest with two adults building the nest. Enjoy these photos.
I received the following notice from the Peregrine Fund tonight. We have 1 egg in the nest downtown and the camera is up and running, although I did not notice any sound. Maybe later. Again, many thanks to Shawn Carmen for designing this logo. We appreciate your work. There is a hotlink to the Boise Falcon Cam in the sidebar which I will keep active all season. And for now, you can link to the cam From Here. Enjoy!
Welcome to the 2014 FalconCam season! This is the sixth year a webcam has provided you with a front-row seat for watching the daily activities at a nest box in downtown Boise.
We are launching the season with big news – the female Peregrine Falcon laid her first egg today! This is the earliest date for a first egg since the webcam was installed in 2009. The timing is almost two weeks earlier than last year, which also was earlier than ever. Wild birds keep their own schedules.
We appreciate your patience as we continue working on the web page. The video can take up to a minute to load, and the audio is not yet available. You may notice various refinements in the days ahead.
The photo of the falcons at the nest was taken by Bob Young on March 12.
Wow! Can’t believe that it is the First of Spring already! 49° F and about a 10 mph wind blowing. Feels like 45°. Just a little chilly up on the Eastman Garage roof. But worth it. I know there was one falcon there, and maybe two. Hard to tell as I think it was in the back of the box. I did send some photos to the Peregrine Fund and they did acknowledge them. From what I understand from Peregrine Fund posts, there will be a camera installed at the nest when the logistics get worked out and the equipment is installed. I have no idea when that will happen. I will let you know when I know. In the meantime, enjoy these photos and remember to Left-Click any of them to see enlarged. Keep Looking Up!
Yes indeed they are! The Boise downtown Peregrine Falcons are back! They are looking at the nest box (hack box) on the NW corner, 14th floor of the Capital One Building – their “old” nesting spot for several years now. Are they the same ones as last year? I don’t know, but they do have the tendency to return to the same nest area each year. Are they the yearlings from last year? Sorry. I don’t know. Just know and be happy that we have a pair back in downtown Boise to watch. San Francisco and San Jose have 3 eggs each. But for now, just enjoy seeing “our” two birds flying around town creating havoc on the pigeons and sparrows. Enjoy these First of the Season photos I took at 1:18pm this afternoon. I will send copies to the Peregrine Fund and to Bill Bosworth at IDFG. Left-Click to see them enlarged. Keep Looking Up!
Yes. It has been a while! I can tell you this, though. The Boise downtown Peregrines have been spotted around town at different locations and they look healthy. The photo to the left is a Sharp-shinned Hawk that landed in our alley last February and has been seen around the area this year. He has left some “tell tale” signs. Robin forwarded this article to me about how to identify Coopers Hawk and a Sharp-shinned Hawk. It can be extremely difficult. Coopers Hawk and Sharp-shinned Hawk from Feederwatch. From the article,
Sharp-shinned (Accipiter striatus) and Cooper’s (Accipiter cooperii) hawks commonly prey on feeder birds, and they are frequently reported by FeederWatchers. Despite their common occurrence, these hawks present a significant identification problem for many beginning and intermediate (and even more advanced!) birders. There is great variation in plumage and in size for these two species. Therefore, perhaps more than any other similar-looking birds, no single field mark is likely to distinguish one species from the other. Instead, the careful observer must use a combination of field marks and draw from the overall “gestalt” of the hawk for proper identification. No field guide will substitute for plenty of practice in the field.
If you participate in Project FeederWatch, observed one of these two hawks during a FeederWatch count, and are not absolutely certain which hawk you observed, please report the bird as an “Accipiter sp.” (the genus in which these two species are classified).
If you are going to participate in the Great Backyard Bird Count (GBBC), and this is a national event, you can get information from the site listed above. It is free and they do provide you with all the information and resource you will need. Cheers and Keep Looking Up!
