=Ruddy Duck=: _Oxyura jamaicensis rubida_ (Wilson).--This is a local summer resident in marshland; numbers seem generally higher in western than in eastern Kansas. The season of greatest abundance is March through November, but numbers are conspicuously reduced in midsummer. _Breeding schedule._--Eggs are known to be laid in May and June. _Number of eggs._--Clutch-size is about 10 eggs (Davie, 1898). Nests are placed near the edge of water, either in or on emergent marsh vegetation; nests of other marshland birds, such as coots, are sometimes appropriated (Davie, 1898). =Turkey Vulture=: _Cathartes aura teter_ Friedmann.--This summer resident is common throughout Kansas. Occurrence in time is indicated in Table 11. _Breeding schedule._--Fifteen records of breeding span the period April 21 to June 10; earlier records will doubtless be found, to judge from the frequency distribution of the present sample. The peak of egg-laying is perhaps around May 1. _Number of eggs._--Clutch-size is 2 eggs (1.8, 1-2; 12). Nests are placed in holes and crevices in trees and cliffs, on rocky ledges, and the like. [Illustration: FIG. 3.--Histograms representing breeding schedules of two herons, the Red-tailed Hawk, Bobwhite, and two shore birds in Kansas. See legend to Figure 1 for explanation of histograms.] =Black Vulture=: _Coragyps atratus_ (Meyer).--This is possibly a summer resident in the southeastern sector of Kansas. There is one nesting record, for Labette County (Goss, 1891:245). _Breeding schedule._--There are no data for this species in Kansas. _Number of eggs._--Clutch-size is 2 eggs (Davie, 1898). Nests are placed in hollows (logs, stumps, _etc._) on the ground surface. =Swallow-tailed Kite=: _Elanoides forficatus forficatus_ (Linnaeus).--This kite was formerly a summer resident in eastern Kansas; it no longer occurs as a breeding species. _Breeding schedule._--In Kansas the season seemed to occur relatively late in the year for a raptor; eggs were laid in May, so far as is known. _Number of eggs._--Clutch-size is about 2 eggs (Davie, 1898). Nests are placed in tops of trees. =Mississippi Kite=: _Ictinia misisippiensis_ (Wilson).--This is a common summer resident in southern Kansas, west to Morton County. Specimens taken in the breeding season and records of nesting come from south of stations in Grant, Barton, Harvey, and Douglas counties; the present center of abundance is in Meade, Clark, Comanche, Barber, and Harper counties. _Breeding schedule._--Seven records of breeding span the period April 20 to June 10; the peak of egg-laying seems to be in the first week of May. _Number of eggs._--Clutch-size is 2 eggs. Nests are placed about 35 feet high (from 25 to 50 feet) in cottonwood, willow, elm, black locust, and the like.
