Incubation Constancy in the Red-Winged Blackbird
INCUBATION CONSTANCY IN THE RED-WINGED BLACKBIRD LARRY C. HOLCOMB Avian incubation behavior is affected by a multitude of exogenous and en- dogenous factors. Kendeigh (1952, 196313) and Skutch (1962) reviewed in- cubation in many different orders of birds and discussed factors affecting the amount of time spent in incubation. Among workers recently reporting on incubation behavior in wild passerines are Prescott (1964)) Mumford (1964)) Erpino (1968)) Maxwell and Putnam (1972)) and Morton et al. (1972). In the Red-winged Blackbird (Ag e1 aius phoeniceus) , Nero (1956a, 195613) has published observations on female behavior during the repro- ductive cycle, but nothing was reported on the incubation constancy (per- cent of daylight hours spent on the nest). I have reported (Holcomb, 1968, 1970) that female Redwings incubated normal-sized artificial eggs a mean of 19.4 days before abandoning them. This is 8.4 days beyond the normal incubation period. The present study was designed to determine the incubation constancy in the egg-laying period, to discover if it increased each day as the incubation behavior developed, and to find if there was less incubation each day as females neared the day when eggs were abandoned in prolonged incubation. METHODS I studied the incubation behavior of Red-winged Blackbirds near Omaha, Nebraska, in 1968 and 1969. Birds were breeding in a variety of habitats, including weed, alfalfa, and clover fields, hedgerows, ditch banks, and marshes. I visited the nesting areas nearly every day, beginning in March and ending in August. Male Redwings generally arrived in early March and females soon afterward. -

Care of Fertile Eggs Prior to Incubation 1
CARE OF FERTILE EGGS PRIOR TO INCUBATION 1. Keep eggs at 50º - 60º F (room temperature). (DON’T PUT IN A REFRIGERATOR, IT IS TOO COLD!) 2. Store the eggs with the BIG end up in egg cartons. 3. You can store for 10 days after they have been laid before hatch rate decreases (50% hatch rate is a good rate). Incubation / hatching time begins once the eggs are placed in the incubator and brought up to 99 ½ºF. Count day 1 after first 24 hours. Incubation/hatching time for chickens are 21 days and 28 to 33 days for ducks. INCUBATOR SET UP 1. Place the incubator(s) away from any windows as the sunlight will magnify thru the plexi-glass cover making it too hot. 2. Set up the incubator four (4) hours prior to adding eggs; it will give the incubator an opportunity to Diagram #2 Round Corner regulate the water temperature in the reservoir. Diagram #1 Put water into both of the troughs on the square Square corner incubator incubator cornered incubators (see diagram #1). In the round corner model which has a larger and smaller trough, place water in the outside trough labeled “circulating” (see diagram #2). (Be sure that the incubator turns on at 99º and off at 100ºF.) 3. Place the plastic thermometer, simply lay it across the top of the eggs, (see diagram #5). It will basically ride on top of the eggs. 4. Cover the adjusting stem on top with paper cup taped to help eliminate the likelihood of the setting being accidentally changed. -

Galliform Baraminology 4 Abstract This study investigates the number of galliform bird holobaramins. Criteria used to determine the members of any given holobaramin included a biblical word analysis, statistical baraminology, and hybridization. The biblical search yielded limited biosystematic information; however, since it is a necessary and useful part of baraminology research it is both included and discussed. -
Class Three: Breeding
Class Three: Breeding WHERE DO SEABIRDS LAY THEIR EGGS? Nest or no nest? • Some species use no nesting material. E.g., the white tern lays a single egg on an open branch. • Some species use a very little bit of nesting material. E.g., the tufted puffin may use a few pieces of grass and a couple of feathers. • Some species build more substantial nests. E.g. kittiwakes cement their nests onto small cliff shelves by trampling mud and guano to form a base. And, some cormorants build large nests in trees from sticks and twigs. [email protected] www.seabirdyouth.org 1 White tern • Also called fairy tern. • Tropical seabird species. • Lays egg on branch or fork in tree. No nest. • Newly hatched chicks have well developed feet to hang onto the nesting-site. White Tern. © Pillot, via Creative Commons. On the coast or inland? • Most seabird species breed on the coast and offshore islands. • Some species breed fairly far inland, but still commute to the ocean to feed. E.g., kittlitz’s murrelets nest on scree slopes on coastal mountains, and parents may travel more than 70km to their feeding grounds. • Other species breed far inland and never travel to the ocean. E.g., double crested cormorants breed on the coast, but also on lakes in many states such as Minnesota. [email protected] www.seabirdyouth.org 2 NESTING HABITAT (1) Ground Some species breed on the ground. These species tend to breed in areas with little or no predation, such as offshore islands (e.g., terns and gulls) or in the Antarctic (e.g., penguins, albatross). -

HYBRIDIZATION & ZOOGEOGRAPHIC PATTERNS IN PHEASANTS PAUL A. JOHNSGARD The purpose of this paper is to infonn members of the W.P.A. of an unusual scientific use of the extent and significance of hybridization among pheasants (tribe Phasianini in the proposed classification of Johnsgard~ 1973). This has occasionally occurred naturally, as for example between such locally sympatric species pairs as the kalij (Lophura leucol11elana) and the silver pheasant (L. nycthelnera), but usually occurs "'accidentally" in captive birds, especially in the absence of conspecific mates. Rarely has it been specifically planned for scientific purposes, such as for obtaining genetic, morphological, or biochemical information on hybrid haemoglobins (Brush. 1967), trans ferins (Crozier, 1967), or immunoelectrophoretic comparisons of blood sera (Sato, Ishi and HiraI, 1967). The literature has been summarized by Gray (1958), Delacour (1977), and Rutgers and Norris (1970). Some of these alleged hybrids, especially those not involving other Galliformes, were inadequately doculnented, and in a few cases such as a supposed hybrid between domestic fowl (Gallus gal/us) and the lyrebird (Menura novaehollandiae) can be discounted. -
Egg Laying in Pet Birds Egg Laying in Pet Birds Can Be a Serious Health Threat
Egg Laying in Pet Birds Egg laying in pet birds can be a serious health threat. This article explains why (and what to do if) your bird starts laying eggs. Providing proper, non-incandescent lighting, a healthy diet, and adequate sleep, as well as removing nesting toys or materials are key to discouraging egg laying. Overview In wild birds and breeding birds, egg laying is a natural, seasonal process. However, female pet birds can also lay eggs, even without the presence of a male. Such eggs are infertile and will not hatch, even if incubated. A bird in the peak of health on an ideal diet may be able to sustain some egg production without serious harm. However, with captive pet birds, it can also become an obsession, because the eggs do not hatch and allow the full cycle to complete, thus turning off the hormonal trigger to lay eggs. Constant egg laying will deplete your bird of vital nutrients, and predispose her to malnutrition , osteoporosis, and life-threatening health problems, such as egg binding and yolk peritonitis. While egg laying can occur in any breed, it is most common in cockatiels, lovebirds, budgies, canaries, and finches. Egg laying can start anytime from 5 months to over 10 years of age. If you find an egg, you want to immediately correct any environmental factors that predispose your bird to lay eggs. If that does not work, your bird may require medical treatment to control egg laying, so you’ll want to get her to a qualified Avian vet. There are several safe, effective hormonal treatments available, which your Avian vet can tailor to your bird's needs. -
Nest Building and Egg Laying by Redwinged Blackbirds in Response to Artificial Manipulations
NEST BUILDING AND EGG LAYING BY REDWINGED BLACKBIRDS IN RESPONSE TO ARTIFICIAL MANIPULATIONS LARRY C. HOLCOMB THE responsesof breedingbirds to many external stimuli have been well reviewedby Lehrman (1959), Eisner (1960), and van Tienhoven (1961). The studiesperformed by Emlen (1941) on the Tricolored Blackbird (Agelaiustricolor) are especiallyrelevant to this paper because of somesimilarities of this icterid to the RedwingedBlackbird (Agelaius phoeniceus).Orians (1961) reportsthe similaritiesand differencesin the ecologyand social systemsof the Redwingedand Tricolored Blackbirds. The objectivesof the presentstudy were to assesssome of the external stimuli that affect physiologicaland related behavioral patterns in the Red-wing. The two nmin objectiveswere to 1) determineresponses of Red- wings to artificial nest manipulations,compared with thosereported by Emlen (1941) for the TricoloredBlackbird, and 2) discoverif Red-wings are determinateor indeterminatelayers. Emlen found that the TricoloredBlackbird usually lays its first egg on the day followingnest completion.Payne (1965) reportsthat Tricolored Blackbirdsusually lay their first eggin the morningfollowing completion of the nestbut that Red-wingfemales have a rangeof 1-4 days. In addition Payne notes that all Tricolored Blackbirds had ovulated on the day of lining the nest, whereassix of eight Red-wing femalestaken from lined nestshad not ovulated. I have made similar observationson Red-wings. Payne statesthat "clutchsize of RedwingedBlackbirds is apparentlydeter- mined by the developmentof the ovary a few days before the final egg is laid." Holcomb and Twiest (1968) present data on the time between nest completionand egglaying for 42 uplandand marshbreeding Red-wings in May and June. Theseshow a meandelay in laying of 2.0 days after nest completion,with a range of between0 and 5 days.
