Welcome to the Swainson's Hawk Watch

May 15, 2015 - A pair of Swainson's Hawks have been mating and building a new nest in a different neighborhood tree. I will try to start adding a few new 2015 photos of this pair as the summer progresses. (Scroll down on this page to see the 2015 blog posts in chronological order.)

Note! These and additional photos are viewable in this Swainson's Hawks blog 2015 Picasa Web album.

Archive, May 2014 two Swainson's Hawks have been mating in a tree about a block from the old 2010 -2011 nest site. I have not seen them in a nest yet but have seen them mate three times in the same tree over a two day period.

Whenever possible I will try to post photos on this blog again this year, especially if we can identify the nest site where we can see the chicks growing and fledgling. Note! See the first photos below on the May 5, 2014 blog post below.

Archive 2010 & 2011.
In April of 2010, a pair of wild Swainson's Hawks decided to nest in our neighborhood in Boise, Idaho. This "Hawk Watch" will attempt to record words and photographs describing the Hawks behaviors, including the hatching & fledgling of chicks over the spring and summer. Many others who live in the neighborhood also watched the daily activities of the hawks and used this blog to keep up on my own observations and photographs.

Note! May 6, 2011 Two Red-tailed Hawks have settled on the old nest and appear to be laying on eggs now. See blog posts below. Here is a link to 56 Red-tailed hawk photographs from 2011 I uploaded to my Picasa Web Album.

Note! On March 12, 2011 two neighbors reported seeing a single hawk flying around and landing on the nest. Hopefully they will nest here again or nearby and we can continue the blog through 2011.
Note! Please Try to "Follow" the Blog and check in often. I am trying to update this site and the photo album at least once or twice a week.

Mother Hawk goes out for more nest leaves

This morning I walked past the nest two times and the second time the Mother hawk was in the often used roost tree closer to the road than the nest.  I waited because I know she won't stay away from the nest for any length of time.  Finally she flew off toward the hay field where the adults hunt and in a few minutes she returned with another tree branch with a bunch of leaves for the nest.  This time she carried the branch in her talons.  Yesterday she carried the branch with leaves in her beak.

Female Hawk gathers more leaves

This morning as I walked past the nest the female hawk was out of the nest and standing on a nearby tree limb.  I watched as she flew away toward the hunting field and soon she returned to the nest with a branch containing a bunch of leaves, possibly to provide shade or comfort for the 3 chicks in the nest.

Female Hawk brings new leaves to the nest

The nest is high in a tree with some leaves at the level of the nest.  The chicks are hard to see unless they poke their heads up.  In the last post I noted that I had seen 2 heads at the same time and a few days ago with binoculars I finally saw 3 heads together as the female hawk fed them.  I will try to get photos of all three together soon.

Meanwhile, the other day  as I walked past the nest  I could not see an adult in the nest.  It was mid day and quite warm.  I waited for a few minutes and one adult flew towards the nest with a beak full of green leaves.  My thought is that the adult is trying to bring more shade or at least a softer bed for the chicks.  In a few minutes the male hawk flew in with a meal for the chicks.

Two Swainson's Hawk Chicks are now visible in the nest

From my last post on May 15,  I have seen and photographed the adults in the air, in various trees and in the nest.  In general it has been pretty quiet for several weeks.  I could see the female hawk sitting on the nest and knew she must be laying on eggs.  Finally two days ago I was able to see one white head poking up and then a second one.  The female flew away and left them alone in the nest for a few minutes and then came back.  The male flew in and apparently left a meal as the female started to feed the chicks.  I am shooting from some distance with a telephoto lens through branches and it is hard to get a very sharp focus, but here are a few of the first Swainson's Hawk chick photos from our neighborhood nest in 2015.

Building the Hawk nest

This Swainson's Hawk flew to the nest with a bunch of leaves in its talons, dropped them off and flew off again.

Swainson's Hawk Female sitting in new nest

On May 3, 2015 the female was sitting in the new nest.

And again on May 4, I saw the female in the nest.

On May 5, one hawk flew to the nest with prey in it's talons.  It may be a squirrel.

Swainson's Hawks flying

On April 30, 2015 with my telephoto lens I was able to get a few good flying photos of the hawks.

Closer view of Swainson's Hawks Mating

On April 30, 2015, I first saw the hawks mating at a distance through the trees.  I walked around the block toward where I saw them and was able to get a much closer view as they mated again in the same tree.  I probably witnessed this mating behavior at least 6 or 7 times in this same tree over a period of two days.

2015 Swainsons Hawks Mating

On April 30, 2015 Iwas able to photograph a pair of Swainsons Hawks mating in our neighborhood.  There appears to be a new nest nearby and the hawks have been flying in and out of it periodically.

Swainsons Hawks Mating

For the past few days I have seen Swainsons Hawks flying and landing in a tree in my neighborhood. On May 2, late in the afternoon, the female was perched in the tree and suddenly the male swooped in and they mated.  After preening at a short distance in the tree the male flew down and they mated again.  Below is link to a PicasaWeb photo album with 20 photos I shot during this time.


Below are three sample photos from the album

Red-Tailed Hawk Cam: Egg hatches in NY.

I found this article about a Red-Tailed Hawk nest in New York where a live web cam has been set up to watch the nest and hatching of 3 eggs.  There was concern that the incubation period had gone on too long and the eggs might not hatch.  However, the web cam recently recorded one egg hatching.

Here is a link to the article.

Red-Tailed Hawks are apparently laying on eggs

I have been watching the old Swainson's Hawk nest and have never seen any evidence that the Swainson's have come back.  Meanwhile a pair of Red-Tailed Hawks have clearly taken over the nest and are apparently laying on eggs now.  These could be hatching any time and I will try to photo document what I see during the summer.  If we see chicks I may start a new blog for the Red-Tailed Hawks.

I have uploaded 56 Red-Taiiled photos around the nest I have taken to a Picasa Web Album .

Below is a good close up shot of one of the birds flying above the nest..

Red Tail Hawk visiting 2010 Swainson's Hawk Nest

Yesterday evening as it was cloudy and getting dark I finally did see and photograph a hawk coming back and forth to the 2010 Swainson's Hawk nest. This Hawk definitely looks like a Red Tail Hawk as Bill from the Conservation Research Foundation suggested it might be.  Last year it was about mid april before we started seeing the Swainson's Hawks.  I guess we will have to wait a little longer.  I doubt that a Red Tail Hawk would use this nest for the summer, but we will find out as time goes by.

  Below are a few photos highlighting the red color in the tail of this hawk..

Need to verify Hawk species coming to 2010 Swainson's Hawk nest.

I have been in communication with local Hawk research scientists about the Swainson's Hawk nest and reported to them yesterday that neighbors had been seeing at least one hawk visiting the old nest several times this past week.  However, I received the following message today noting that this would be a very early date for Swainson's Hawks to return to Boise and we should try to get a more positive identification.

Thanks, Gary.
We see many Swainson’s nests with local red-tails near them early in the year.
You might visit that site to determine whether or not the hawk in question is actually a Swainson’s. If so, March 12 is probably a record for early arrival.
Let me know. We appreciate your interest and good observations/photography of this species!
Conservation Research Foundation
I have not yet seen any of the Hawks or been able to photograph one. I would like to ask any of the neighbors who see the hawks again to try to get a positive ID and a picture if possible.

FYI,  Here are links to photo ID sites for Red Tail Hawks and Swainson's Hawks from the Cornell Lab of Ornithology/ All About Birds web site.

Swainson's Hawk Reappears at Boise, Idaho Nest on March 12, 2011

On Sunday, March 12, 2011 a neighbor who lives across the street from the 2010 Swainson's Hawk nest observed a single hawk flying around and landing on the old nest.  Later I heard from another neighbor who lives a block away that he saw one that same day land on the same nest.  Another neighbor saw one sitting in the nest early in the evening during the week and today another neighbor called me about noon to report that he saw one just land and sit on the nest.  I rode my bike over then with my camera, but did not see the hawk on the nest or in the sky flying.

This is almost a month earlier than we saw them near this nest last year.  We hope these visits will mean that they may try to use the same nest again.  I will continue to update this blog with reports of sightings and photographs as often as possible.

On the VirtualBirder.com web site there is a report on March 10 from the National Birding Hotline Cooperative, that in the Los Angeles,  California area -

SWAINSON’S HAWKS are moving through, with a flock of 15 reported near Newhall
Pass on March 4.  Single birds were also over Claremont on March 3 and 4.

On March 16,  "The Birding Lists Digest" Hawk Watch report from the Santa Ana NWR, near Alamo Texas, there is a report of 2 Swainson's Hawks.
