    Red-Winged Blackbirds: II. Pigmentation in Epaulets of Females
    (1980-09) Miskimen, Mildred
    This study describes color changes in upper secondary coverts (epaulets) of female red-winged blackbirds (Agelaius phoeniceus) in successive molts. The methods used included Munsell color chips and microscopic examination of feathers. Examination of feathers collected from these upper secondary coverts showed color pigments distributed in barbs and barbules of distal feathertips. Yellow pigments predominated in juvenile and first-winter females and orange and rust in secondwinter and older birds. Rust color resulted from dark hamuli on orange barbules; in the absence of melanin in hamuli the feather appeared orange. No appreciable color changes appeared after the second winter plumage. Females with pure red feathers were not found among the redwings studied. Effect of diet on pigmentation could not be ascertained by the methods used.

    Red-Winged Blackbirds: I. Age-Related Epaulet Color Changes in Captive Females
    (1980-09) Miskimen, Mildred
    Twenty-four female red-winged blackbirds (Agelaius phoeniceus) were trapped when juveniles and held captive during 3.5 years of observation. Color changes in upper secondary coverts (epaulets) of wings occurred at the time of the late-summer molt of the birds' first and second years. About 84% of birds had dilute rust epaulets after their first molt; 16% had orange. After the molt of the second year, 100% of the birds acquired bright rust or orange epaulets. Thus, outside of the later-summer molting period, females with orange, rust or red epaulets would by chance be 86% after-second-year birds and 14% second year birds. Observations of females caught in fall banding operations supported these findings; 10% of 109 birds in their first winter had bright rust or orange epaulets, and 90% had dilute rust epaulets.

    Trophic Assessment iof Ten Publicly-Owned Northeastern Ohio Likes
    (1980-09) Olive, John H.; Karn, Barbara Parish
    Trophic assessments of 10 publicly-owned northeastern Ohio lakes including Aquilla, Baldwin, Findley, Hinckley, Hodgson (Muddy), Spencer, Lower Shaker, Upper Shaker, Virginia Kendall, and Wallace indicated that all were highly eutrophic. Criteria for these assessments were based on a Trophic State Index developed by the U.S. Environmental Protection Agency that incorporated epilimnetic levels of total phosphorus, dissolved phosphorus, inorganic nitrogen, dissolved oxygen, and chlorophyll a and Secchi disk water transparency into a single numerical index of trophic status (TIN). The most eutrophic lakes were Spencer, which had been purposely enriched to increase productivity, and the Shaker Lakes, which were enriched by storm water overflows of sanitary sewers. The least eutrophic lakes were Hodgson, Aquilla, Virginia Kendall, and Wallace reflecting relatively better watershed protection from soil erosion and domestic organic wastes.

    Comparison of Ohioans' Perceptions of Strup Mining and Reclamation in 1970 and 1975
    (1980-09) Ray, John R.
    In 1970 and again in 1975, the population of Ohio was sampled to determine how Ohioans felt about strip mining and reclamation in the state. Among the several items provided by respondents participating in the study was their opinion regarding these 2 closely related activities. In addition, the respondents were asked to give a reason for their opinions. In 1970, the proportion of the sample was equally divided between those favorable toward strip mining and those opposed to the activity. About 0.25 of the sample assumed a neutral stand toward the concept. The predominant reason given by those favoring strip mining was their belief that strip mining satisfied a demand for power and fuel. Those opposed to the activity were primarily concerned over the environmental destruction they associated with the activity. In 1975, the proportion favoring strip mining was twice that found in the earlier study. Those assuming a neutral position represented a very small proportion of the population. The same reason for favoring the activity predominated. Positive opinions on reclamation were overwhelming in 1970. However, reasons given by respondents for their opinions varied as they perceived future needs for land. Positive opinions were expressed by an even greater proportion in 1975. Reasons given were the same as in 1970, except that a perception of a current need for land appeared in responses received in 1975. Apparently, opinions on strip mining and reclamation became more polarized over the 5 year period of the study.

    Pesticide Analysis, Egg and Eggshell Characteristics of Red-Tailed Hawk Eggs
    (1980-09) Springer, Mark Andrew
    In this study, addled and viable Red-tailed Hawk eggs were compared in terms of pesticide levels, egg and eggshell parameters, and shell ultrastructure as determined by scanning electron microscopy. These values were then used to compare actual measurements against egg and eggshell indices commonly reported in the literature. Addled eggs of Red-tailed Hawks were of greater length, weight and volume than viable eggs, while viable eggs showed greater shell weights and thickness than addled eggs. The general structure of the eggshell consisted of 3 layers: shell membrane, mammillary layer and palisade layer. No cuticle was present. No differences in thickness of the shell membrane or mammillary layer were detected between addled and viable eggs; however, the palisade layer was found to be 24% thicker (X2, P<0.05) in viable eggs than in addled eggs (0.11 ±0.03 mm and 0.08±0.01 mm, respectively). The thicker palisade layer resulted in an overall thicker eggshell in viable compared to addled eggs (0.28±0.02 mm and 0.25±0.03 mm, respectively). Extensive areas of cavitation in the mammillary layer were found in many addled eggs, but never in viable eggs. Pore channels originating at the membrane layer could be seen extending to the outer surface of the egg. All egg samples analyzed for pesticide residues bore measureable amounts of PCB and DDE, while some samples contained dieldrin and heptochlor epoxide.
