          An adult male, 67Z [Szell], fledged in Toledo OH in 1988, was paired with a hybrid peregrine × prairie falcon (presumably produced in captivity by artificial insemination). Efforts to capture and remove the female failed. They did not nest. Szell 67Z had previously been on territory in Cleveland in 1990 and 1991.

In 1992, a male peregrine, Szell 67Z, was paired with a hybrid female peregrine × prairie falcon (Falco peregrinus × F. mexicanus); the same pair was here in 1993. Wildlife personnel trapped the hybrid female on dummy eggs on April 29 and removed her. A juvenile female peregrine, Zenith 23W, wild-produced in Omaha, Nebraska, in 1992, and the two mated. Male 67Z, now five years old, and the young female then produced three eggs by early June; two hatched and one male and one female young fledged, August 8 and 13 respectively.

Six-year-old male Szell 67Z paired for the secont time with female Zenith 23W, now two years old. Two adults were seen on February 2. In late March, female Sunrise 55R appeared, perhaps during an absence of Zenith. Sunrise, originally hacked in Cincinnati in 1991, was in Detroit in 1993 and was reported in Detroit on March 21, 1994; then she was seen in Cleveland from March 24 to March 31, when her band was read. A major territorial battle occurred on April 2, probably the date of Zenith's return from her winter sojourn. Both females locked talons at the nest ledge, then fell struggling to a fourth floor roof, leaving Sunrise, who dropped a soft-shelled egg in the fight, able only to fly weakly. She recovered, left Cleveland, and was seen again back in Detroit by April 12. Szell and Zenith then produced four eggs by about April 22; all four hatched around May 27, and four males fledged around July 8.

Eight-year-old male Szell paired for the fourth time with four-year-old female Zenith 23W. Four eggs were laid by April 11, all four hatched May 17, and three young fledged, two females and a male, in late June. One young was knocked from the ledge near the nest tray by the adults during defense of the site at banding; it was killed in the fall. An early egg was laid here and never incubated; David Scott, Ohio Division of Wildlife, suspects it was laid by a different female.

Nine-year-old male Szell 67Z paired for the fifth time with five-year-old female Zenith 23W. Between March 13 and April 5, four eggs were laid, possibly by a different female. A partial band reading suggests that Zenith was present at this time. On April 16, seven eggs were seen and Zenith was identified on the nest. The eggs were candled and found not to be viable. The eggs were removed and by May 19 a new clutch of four eggs was being incubated. Hatching began on June 19 and all four young were banded and fledged by August 1. On August 4, one of the young was found dead on a ledge near the nest site, cause unknown. Another young, found with a broken leg at Sandusky, Ohio, on September 17, died the next day at TRC.

Male Szell 67Z was replaced by five-year-old male Bullet 2/*G, hacked in 1993 in Akron, Ohio. Bullet paired with six-year-old female Zenith 23W, nesting here for her sixth year. Four eggs laid in mid-April hatched by May 22. Four males fledged by July 1.
Summary: Szell 67Z (Terminal Tower, Cleveland OH), 16 young, 5 seasons; known or presumed dead.

Six-year-old male Bullet 2/*G, here for the second year, paired again with seven-year-old female Zenith 23W, nesting here for her seventh year. On March 17, Zenith, who migrates each year, evicted female Clearpath *5/A (see pair 86), who had arrived on the site in late winter, in a dramatic but non-fatal battle. Four eggs laid by April 12 hatched in mid-May. Four young males fledged by June 26.

Eight-year-old female Zenith 23W, nesting here for her eighth year, paired with a new male, Buckeye *R/K, fledged wild in 1996 in Columbus, Ohio. Buckeye *R/K was at Case Western Reserve in Cleveland in 1998 and 1999, but did not nest successfully there. Four eggs were produced, three hatched, and three male young fledged in late June. This pair were listed as “SP” (Successful Pair) for the first time.

Nine-year-old female Zenith 23W, nesting here for her ninth year, paired with five-year-old male Buckeye *R/K, here for the second year. They produced four eggs and fledged four young, two of each sex, in the first half of July.
Female Clearpath *5/A arrived at Terminal Tower early, paired with male A/2 (fledged in Pittsburgh in 1992), and produced at least one egg. On March 23, Zenith 23W arrived and a well-photographed fight ensued, producing injuries to Clearpath *5/A that resulted in her death on the way to rehab. Zenith and Clearpath also had a dramatic battle at Terminal Tower in 1999. The replacement in 2001 of male A/2 by Buckeye *R/K probably happened by mid-April. Dave Scott, Ohio Division of Wildlife, thinks it is highly likely that Buckeye *R/K fertilized Zenith’s eggs.

Ten-year-old female Zenith 23W was killed on March 29 in a fight with female S/*W, fledged in 1999 at Gulf Tower, Pittsburgh, Pennsylvania. S/*W nested last year at LTV Steel, Cleveland. She paired at Terminal Tower this year with six-year-old male Buckeye *R/K, here for the third year. They produced four eggs and were halfway through incubation before the return of Zenith 23W. [In last year’s fight here, Clearpath *5/A was still laying when Zenith 23W showed up and killed her.] Four young, three males and a female, fledged in early June this year.
Summary: Zenith 23W (Terminal Tower, Cleveland OH), 31 young., 9 seasons, 3.4/season; known dead.

(1:2)   Ten-year-old female b/r S/*W, here for the eighth year, paired again with thirteen-year-old male Buckeye b/r *R/K, here for the tenth year.
Buckeye died November 17, 2009, having struck a building, possibly during a battle with another male. He had sired 34 young by two females.
In December S/*W was seen in the company of a new, quite large male, later identified as Ranger B/92 (USFWS band 1126-06441); courtship/pair bond displays were observed at the nest box and elsewhere. Ranger B/92 fledged in 2008 at the First Energy Plant in Eastlake, Ohio.
