Banding Highlights 2010

MOBL recoveries were similar to last year at 158, and TRES recoveries were down slightly at 215 from 233 last year. See Tables 1 and 2 – Summary of 2010 Recoveries for distance moved, whether banded as an adult or young, and age distribution.
Notes - MOBL = Mountain Bluebird. TRES = Tree Swallow. The term recovery used below is a generic term for birds that are found dead or alive. Most of the birds listed will have been recaptured alive and released.

Long Distance Bluebird Recoveries
Ron Reist recovered 2231-92630 on his East Olds trail, which was banded by Pres Winter 6 miles west of Viking, AB as a young in 2009. It moved 196 km (121 mi) SW. This is the second MOBL recaptured by Ron that was banded by Pres Winter. The first was in 2006.
Don Conrad recovered 2231-26410 on his trail west of Longview, which was banded as a young in 2009 by Ray Harris north of Pincher Creek. It moved about 100 km (62 mi) N.

Two others, which moved significant distances were:
2291-35531 recovered by Walt Glanville E of Water Valley, banded by Ron Reist as a young in 2008 E of Olds, moved about 60 km SW.
2261-76265 recovered by Shonna McLeod on Hwy 773 SW of Calgary, banded by Don Conrad as a young in 2007 SW of Nanton, moved about 59 Km NNW.

Long Distance Tree Swallow Recoveries

Don Stiles recovered 2221-27598 on his East Didsbury trail. This bird was banded by Russ Dawson west of Prince George, BC. It had stopped 667 km (413 mi) SE of its banding location. Unfortunately, the number could not be checked the next week as a different female was the one sitting on the newly hatched young.
Russ Dawson is a biology professor at the University of Northern BC. He and his graduate students have four study areas west of Prince George, BC. They study various aspects of reproductive ecology of birds, including mate choice, parasitism, etc. He also has a study area for Mountain Bluebirds southwest of Williams Lake, BC.

Dick Stauffer recovered 2311-99146 in a nest-box on the Olds Golf Course. It was banded by Don Conrad west of Longview as a young in 2008. It had moved 140 km (87 mi) NNE, which is from the southernmost trail on Calgary Area Nest-box Monitors to one of the northernmost. Fortunately, this number was rechecked by Dick.

Walter Gruszecki recovered 1921-96110 on his trail west of Innisfail, which was found to be a bird banded by Hardy Pletz as a young in 2008 near Millet, AB. It had moved 130 km (80 mi) S.

2311-89537 was recaptured by Ron Reist on his East Olds trail. This bird was banded as a young in 2008 by George Loades on his Jumping Pound trail, and moved about 98.5 km (61 mi) NE.

2311-87395 was recaptured by Ray Woods on his Elkton trail west of Didsbury. It was banded by Barry Trakalo as a young in 2008 NE of Millarville, and moved about 90.5 km (56 mi) N.

This makes 5 TRES recovered at distances greater than 80 km (50 mi), a record for Calgary Area Nest-box Monitors. Usually we have only one or two.

Nancy Davis recovered TRES 2311-87229 on her Sibbald Creek trail (Hwy 68). It had been banded as an adult by Bill Taylor in 2009 N of Okotoks, and moved 42 km (26 mi) NW. This is a considerable distance for a bird banded as an adult to move.

We learned in 2010 of a TRES recaptured in a mist net at Inglewood Bird Sanctuary in 2009 by Bill Taylor. This bird had been banded as a young in 2007 in the Jumping Pound area by George Loades, and moved about 37 km E. This is the second time we have been involved with a TRES at Inglewood Bird Sanctuary. In 2008 a TRES recaptured there was banded by Pat Mitchell as a young in 2005 in the Big Hill Springs area, and moved 37 km SE.

Oldest Birds
The oldest bird recovered this year was a TRES banded by Isabelle Orr as an adult in 2004 making it the only 7-year old bird recovered.
There were 3 each of 6 year old MOBL and TRES recovered.
The 3 MOBL were recovered by Don Stiles, Andrew Holder, and Ray Harris.
The 3 TRES were recovered by Don Stiles, Ray Woods and Bill Taylor.
Bill Taylor had three 5-year old TRES recovered and Nancy Davis had two, both banded as young in 2005 on George Loades’ adjacent Jumping Pound Trail by Christi Beckmann. Christa was doing a research project on that trail from 2003 to 2005.

Ron Reist and Dick Stauffer each had 5-year old MOBLs recovered. Ron’s bird was reported recaptured in the same box 5 years in a row, and Dick’s was recaptured in 2007, 2008 and 2010.
8 of the 14 older birds listed above have records of additional recaptures since being banded.

Site Fidelity
MOBL 1951-73812 was recaptured by Shonna McLeod in the adjacent box to where it was first recaptured in 2009. It had been banded as a young in 2007 by Brian Keeling west of Stavely. The first time it moved 73 km NNW.

MOBL 2201-46568 was banded by Marijke Jalink-Wijbrans as a young in 2006. In 2007 it moved 13 km NE to George Loades trail. In 2010 it moved SW about 16 km to Lenora Brown’s trail. It is unusual to find a bird that moved farther the second time.

Dick Stauffer recaptured a TRES banded as a young in 2009 that returned to the same box in 2010. This is unusual but it has happened before.


Same Year Recoveries
Ron Reist reported a recovery of MOBL 2231-14103 on June 16. It was originally banded by Don Stiles on June 1. It had moved 12.6 km (7.8 mi) NNW after its first nest failed. This is a considerable distance for movement within a single year.

Dick Stauffer reported a male TRES banded on June 24 that had moved to the adjacent box on July 15 with a different banded female.

Cross trail recoveries of interest
Barry Trakalo again reported most of his recoveries were cross trail recoveries as follows: 7 MOBL and 1 TRES. He also had 1 MOBL recovery and 2 TRES recoveries of birds banded on his own trail. This pattern of mostly cross trail recoveries has been noticed on Barry’s trail in recent years as his trail is surrounded by other trails where monitors band their birds.

All of the 5 TRES recovered on Nancy Davis trail were banded on other trails, mostly on George Loades’ trail adjacent to the east. She recovered one of these on her trail in 2008.

Pat Mitchell recaptured 3 TRES that were banded on Isabelle Orr’s trail adjacent to the east. She recaptured the first bird banded by Isabelle in 2009 and in 2008 (both as adults), and a young banded in 2007.

It was noted that TRES on cross trails this year, recaptures of birds that were originally banded as young were mainly banded as young in 2008. For TRES banded as young the numbers were: 2009 – 3, 2008 – 15, 2007 – 4, 2006 – 1 and 2005 – 1, Total 24.
The reason for this is not known.
A more expected distribution was noted for MOBL. For MOBL banded as young the numbers were: 2009 – 16, 2008 – 5, 2007 – 4, 2006 – 1 Total 26.


Ron Reist TRES recaptures
Ron Reist recaptured 69 TRES, all banded as adults, a number is well ahead of any other bander. One of the reasons for this is that he banded more adults than young in the past two years. The year banded and number recaptured for these birds was: 2009 – 46, 2008 – 16 and 2007 – 7. 19 of these were recovered in the same box where they were banded (or the adjacent box of a pair). Most of the others were recovered within 1.6 km of where they were banded. Only 4 moved distances greater than 5 km.
