Here are two pictures of the only young kite in Rockford that we know about. It left the nest today, at age 32 days. (Our best estimate.)

There are two nests of Mississippi Kites under construction by two different pairs of birds. Construction of the first one probably began on 12 May. The second nest was under construction on 20 May, and from its size then, my guess is that it was started around the 17th. The males are building, with females often perched nearby, not always on a conspicuous perch. The birds frequently call to each other.

First, a bit of history. In 2008, the first Rockford kite nest was found in a deciduous tree at Bloom School. A nest was found in 2009 in a pine near Luther and Pioneer. A nest was found last year in a pine tree near Buckingham and Fairview Court, and we have reason to believe that the same nest tree was also used in 2009. (It is not being used this year.) All of these nests were located just before birds fledged and left them; none were located during construction.

In addition to adult birds seen those years, the following birds were recorded:

2008: 1 fledgling
2009: 1 fledgling, 1 subadult
2010: 3 fledglings, 1 subadult male

No subadults have yet been seen this year.

Rockford appears to be in the vanguard of a significant Mississippi Kite range expansion. We can contribute useful information about this expansion by monitoring population size and changes here in Rockford. It is difficult to differentiate individual adults—we can’t mark them—so the best way to be sure of a minimum population size is to associate them with nests. Your observations can help with this, but only if you report them.

Kites soaring in the sky feeding (or whatever) cover a wide area and don’t indicate where nests might be. The nests located so far were found by cruising streets in the morning, between 6 and 10, listening for kites, and hoping to catch sight of low-flying birds. Nest-building occurs primarily in the morning, around 6 to 10, before birds go out to feed. If you see or hear low-flying / calling birds in an area, please let us know where that is by calling me at 815-877-6229 or Dan Williams at 815-979-8335. We think that the extended Bloom School area in which kites might be nesting is bounded by Highcrest and Rural on the north and south, and by Parkview and Chelsea on the west and east. I believe that last year, in addition to the spots where young birds were found, kites could have nested, successfully or not, just south of Guilford near Woodlane, and west of James near Barrington Place.

I started systematically criss-crossing the Bloom School neighborhood a week ago, watching for kites. Others have searched as well. After 45 minutes of searching this morning, at 9:20 I saw a strikingly handsome male Mississippi Kite circling low over last year’s known nest tree near Fairview and Buckingham. I watched it for 10 minutes as it circled higher and higher and eventually disappeared very high in the sky east and well south of Bloom School. I saw no other kites. Please post to this blog any significant kite observations you make, such as different or multiple individuals, or locations other than this neighborhood.

On Thursday, September 16, Dan Williams saw an adult and a juvenile. At a different time, I saw the juvenile flying very strongly. We were both out of town for a couple of days after that, and wonder if anyone else has seen any of the kites since last Thursday. If so, please comment on this post, giving date and details. We want to determine the departure date of the last kite. Thanks.

After birding yesterday with Dan & Barb (see previous post), Donna and I went by the intersection where juvenile kite #2 (Kid 2) was seen last Wednesday and again Friday (see 1 Sep post). We found a third juvenile kite perched on a branch 40-45 feet up in a pin oak on the northeast corner of Lundvall and Parkwood. We were able to show it to out-of-town photographers and to many residents of the neighborhood who came by to see what was going on. The kite remained on that branch until around 9:30 this morning, when it moved to a lower branch about 25-30 feet up in the same tree. We have no reports of this bird being able to fly yet.

After checking on this new “Kid 3″ this morning, Donna and I happened to discover a fourth juvenile kite sitting a two or three feet above its nest not far off Highcrest. That nest is less than 600 feet from the nest we reported here on 13 August. Although we did not see it move, Dan and Barbara Williams saw it fly about 15 feet, without leaving its nest tree. It appears to be about the same age as Kid 3.

A summary of sighting histories of these four young kites has been posted on IBET with the same title as this post.

Kid 4 today

Dan and Barbara Williams and I assaulted the intersection of Parkwood and Lundvall (just south of Bloom School) this morning, radios in hand, to cast a dragnet for nesting activity. Previous observations, especially last night, gave reason to believe a nest might be near here. After more than two hours of work, success! A juvenile was discovered that is capable of flying short distances. There is some reason to believe it may have a sibling, but there is as yet no confirmation of that.

Since our suspicion about nesting here was correct, I’ll go out on a limb (no pun intended) and say that we suspect there is yet another nest somewhere south of Guilford.

Very surprising is a report from two knowledgeable observers who live south of Guilford on Parkwood. Monday evening, in advance of a weather front, they watched a flock of 9 kites circling together over their house.

I have updated the map here to reflect these observations. Note that you can zoom in and out, and read details either on the key at left, or by clicking on the markers.

Weekend birders traveling to Rockford to see kites might like to know that they were very conspicuous around 11:00 today. Donna and I saw them as soon as we got to Stratford and Buckingham. Between there and west of James on Burrmont, we saw at least four, and probably five, adult kites. At James and Pelham, we had two adult males together only 50 feet over our heads. We saw kites north of Highcrest, but not at the school or south of there. They were putting on quite a show in this beautiful, breezy weather, flying at less than 200 feet altitude most of the time. There was hardly a period for 15 minutes that one was not in sight as we cruised around looking for (and not finding) a young bird.

Around 1:30, we detoured from errands to run by Oliver Road. Along the oxbows there, we found 26 Great Egrets and perhaps 100 shorebirds. In order of abundance, they were Killdeers and Lesser Yellowlegs, Pectorals, Semipalmated Sandpipers, Snipes, Spotted Sandpiper, and Wilson’s Phalarope. Certainly worth checking again tomorrow morning—heat haze won’t be a problem, and something really good could drop in at any time.

Donut lovers: Edwards Orchard store on Cemetery Road opened today.

The Buckingham Drive juvenile’s primaries have now grown to expected length, beyond the end of its tail. Not surprisingly, it can now fly short distances. Late this afternoon, I watched it fly about 50 feet, from one tree to another. This is apparently the first day it has been capable of flight. According to the current literature, this would put its age at 30 to 35 days. (Literature I am citing is the comprehensive report by Jim Parker for Cornell Laboratory of Ornithology’s Birds of North America Online.)

This bird is about a week ahead of the schedule we observed for juveniles in 2008 and 2009. It should be a reluctant flier for the next 15 to 20 days, frequenting the nest area. It will not attempt to catch insects with adults until age 50+ days, so the adults will continue to feed it. Parental feeding will become infrequent after 60 days. On such a timetable, we could expect to see kites in Rockford until at least September 16-21. This is about as long as they stayed the last two years.

As yet, there is no positive indication that the adult kites in other areas around Bloom School have raised young. We have been closely monitoring their activities, and none of them appear to be making repeated feeding trips to a nest site. Certainly, none of them have a young bird following them around begging for food, as would be the case had juveniles left the nest.

If you do happen to see a young bird associating with adults, please report the time and place and particulars so that we can gain knowledge of how this possible range extension is proceeding. Observe carefully, however—young Cooper’s Hawks are about the same size, and are also brown and streaked. They have been seen circling over Bloom School with adult kites several times recently. You can report by commenting on this report, or by using the numbers at Rockford-MIKIs.

The young kite seen in the nest last Friday was found on the ground yesterday morning by Chicago birders. It may have fallen out as long ago as Saturday. It cannot fly yet. In fact, it has a hard time perching on thinner branches, and occasionally tips over and ends hanging upside down, wings akimbo.

Late yesterday afternoon, it somehow crossed a lawn, a street, and another lawn, and climbed into a tall dense bush. Today it has worked its way up to the top of the bush, and from there to a small tree. It appears to be healthy and strong, and having survived this long on or near the ground, we trust it will soon be flying and hunting on its own.

This morning between 6:20 and 6:45, I counted 5 kites perched in the Bloom School neighborhood. The subadult perched for 2½ hours in the big tree near Buckingham and Pleasant View. Other raptors seen nearby in the last 4 days are Cooper’s Hawk, Red-tailed Hawk, Broad-winged Hawk, Turkey Vulture, and today around noon, a Sharp-shinned Hawk soaring with three Mississippi Kites.

The Carolina Wren is singing regularly around the intersections of Buckingham with Roncevalles and Scottswood.

Now two young Mississippi Kites have been seen. A flying juvenile was seen at Bloom School yesterday at 9 AM by Fran Morel of Evanston. We believe this to be the product of a nesting pair from the southern “hot spot” area marked on my map at the link given in the previous post. A second juvenile from the northern “hot spot” was found this morning.

There is a Carolina Wren at the red house across the street from 3306 Buckingham.
