Why Is the Common Grackle Becoming Less Common? Avian Conservation and Ecology 16(2):7
VOLUME 16, ISSUE 2, ARTICLE 7 Horsley, N. P., and M. P. Ward. 2021. Why is the Common Grackle becoming less common? Avian Conservation and Ecology 16(2):7. https://doi. org/10.5751/ACE-01879-160207 Copyright © 2021 by the author(s). Published here under license by the Resilience Alliance. Research Paper Why is the Common Grackle becoming less common? Noah P. Horsley 1 and Michael P. Ward 1,2 1University of Illinois at Urbana-Champaign, 2Illinois Natural History Survey ABSTRACT. Despite a generalist life history and a widespread distribution, the Common Grackle (Quiscalus quiscula) has declined by more than 58% since 1970. In Illinois, where this study was conducted, the current rate of decline is 7.03% annually. We hypothesized that low reproductive success in intensely agricultural areas is driving population decline. To test this, we quantified the nesting success and post-fledging survival of Common Grackles in central Illinois. Over a 2-year period, we monitored 188 nests and tracked the survival of 53 fledglings. Our estimate for nesting success of 0.622 (95% CI: 0.549-0.695) was much higher than the literature average of 0.267. Similarly, although post-fledging survival had not been estimated previously for Common Grackles, our estimate of 0.617 (95% CI: 0.471-0.764) was relatively high compared to that of other songbirds (range: 0.23-0.87). The most important factor influencing these estimates was ordinal date, which had a negative relationship with both nesting success and post-fledging survival. These results suggest that reproductive success is not the primary driver of population decline in Illinois. -
Eastern Meadowlark Sturnella Magna
eastern meadowlark Sturnella magna Kingdom: Animalia FEATURES Phylum: Chordata Two species of meadowlark are present in Illinois: Class: Aves the eastern meadowlark and the western Order: Passeriformes meadowlark. They are very difficult to tell apart by sight, but their song can help identify them. Both Family: Icteridae birds have yellow breast feathers with a large, black ILLINOIS STATUS “v” marking. The white, outer, tail feathers may be seen when the bird flies. The back feathers are common, native brown. The western meadowlark is paler than the eastern meadowlark, and the yellow on its throat touches its cheek. The meadowlark averages nine inches in length (tail tip to bill tip in preserved specimen). BEHAVIORS The eastern meadowlark is a common migrant and summer resident statewide and a common winter resident in the southern one-third of the state. Its whistled song is “tee-yah, tee-yair.” This meadowlark may be seen sitting on fences or wires or flying with short, choppy flaps and a glide. It lives in pastures, hay fields, fallow fields and near row crops. Spring migrants generally arrive in Illinois in March. Migration occurs during the day. Eggs are produced from April through July. The nest is built on the ground. The female constructs the nest of dried grasses in a depression in the ground in a period of about three to eight days. The nest is covered with a domelike, grass canopy, leaving an opening on the side. Two to six, white eggs with red-brown speckles are deposited by the female, and she alone incubates them for the 14-day incubation period. -

This novel coccidian is unusual because it develops extra-intestinally and sporulates endogenously within the prostate gland of its mammalian host. Histological examination of prostatic tissue revealed dense aggregations of spherical and thin-walled tetrasporocystic, dizoic sporulated coccidian oocysts within tubular lumina, with unsporulated oocysts and gamogonic stages within the cytoplasm of glandular epithelial cells. This coccidian was observed occurring concurrently with dasyurid herpesvirus 1 infection of the antechinus' prostate. Eimeria- specific 18S small subunit ribosomal DNA PCR amplification was used to obtain a partial 18S rDNA nucleotide sequence from the antechinus coccidian. -

Ecuador: HARPY EAGLE & EAST ANDEAN FOOTHILLS EXTENSION
Tropical Birding Trip Report Ecuador: HARPY EAGLE & East Andean Foothills Extension (Jan-Feb 2021) A Tropical Birding custom extension Ecuador: HARPY EAGLE & EAST ANDEAN FOOTHILLS EXTENSION th nd 27 January - 2 February 2021 The main motivation for this custom extension was this Harpy Eagle. This was one of an unusually accessible nesting pair near the Amazonian town of Limoncocha that provided a worthy add-on to The Andes Introtour in northwest Ecuador that preceded this (Jose Illanes/Tropical Birding Tours). Guided by Jose Illanes Birds in the photos within this report are denoted in RED, all photos were taken by the Tropical Birding guide. 1 www.tropicalbirding.com +1-409-515-9110 [email protected] Tropical Birding Trip Report Ecuador: HARPY EAGLE & East Andean Foothills Extension (Jan-Feb 2021) INTRODUCTION This custom extension trip was set up for one person who simply could not get enough of Ecuador…John had just finished Ecuador: The Andes Introtour, in the northwest of the country, and also joined the High Andes Extension to that tour, which sampled the eastern highlands too. However, he was still missing vast chunks of this small country that is bursting with bird diversity. Most importantly, he was keen to get in on the latest “mega bird” in Ecuador, a very accessible Harpy Eagle nest, near a small Amazonian town, which had been hitting the local headlines and drawing the few birding tourists in the country at this time to come see it. With this in mind, TROPICAL BIRDING has been offering custom add-ons to all of our Ecuador offerings (for 2021 and 2022) to see this Harpy Eagle pair, with only three extra days needed to see it. -
Spatuletails, Owlet Lodge & More 2018
Field Guides Tour Report Peru's Magnetic North: Spatuletails, Owlet Lodge & More 2018 Jun 23, 2018 to Jul 5, 2018 Dan Lane & Jesse Fagan For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. The name of this tour highlights a few of the spectacular birds that make their homes in Peru's northern regions, and we saw these, and many more! This might have been called the "Antpittas and More" tour, since we had such great views of several of these formerly hard-to-see species. This Ochre-fronted Antpitta was one; she put on a fantastic display for us! Photo by participant Linda Rudolph. The eastern foothills of Andes of northern Peru are one of those special places on the planet… especially if you’re a fan of birds! The region is characterized by pockets of white sand forest at higher elevations than elsewhere in most of western South America. This translates into endemism, and hence our interest in the region! Of course, the region is famous for the award-winning Marvelous Spatuletail, which is actually not related to the white sand phenomenon, but rather to the Utcubamba valley and its rainshadow habitats (an arm of the dry Marañon valley region of endemism). The white sand endemics actually span areas on both sides of the Marañon valley and include several species described to science only since about 1976! The most famous of this collection is the diminutive Long-whiskered Owlet (described 1977), but also includes Cinnamon Screech-Owl (described 1986), Royal Sunangel (described 1979), Cinnamon-breasted Tody-Tyrant (described 1979), Lulu’s Tody-Flycatcher (described 2001), Chestnut Antpitta (described 1987), Ochre-fronted Antpitta (described 1983), and Bar-winged Wood-Wren (described 1977). -
Adaptations for Food-Getting in the American Blackbirds
THE AUK A QUARTERLY JOURNAL OF ORNITHOLOGY VOL. 68 OCTOBER,1951 No. 4 ADAPTATIONS FOR FOOD-GETTING IN THE AMERICAN BLACKBIRDS BY WILLIAM J. BEECI-IER A careful study of the American blackbird family (Icteridae) during the past severalyears revealsthat its membershave invaded virtually every food niche exploitedby passerinebirds. The presentinvestiga- tion of the functional modificationsof skull, bill, and jaw musculature in the 38 generasuggests that this successstems initially from a general pre-adaptation permitting an entirely new method of feeding. This paper describesfirst the individual feeding adaptations, then their convergent re-appearancein each of the three major icterid lines. Although the graphic comparisonof the genera is presented in the form of a morphologicaltree of relationshipsin Figures 7 to 10, the full evidencefor these relationshipsis not offered here. The present paper confinesitself rather strictly to the nature of the adaptations themselves. METHODS AND MATERIAL Primarily, the method of investigation has been one of attempting to establish valid correlations between skull structure and known feeding functionsin the various genera. The diet of North American specieswas determined from the stomach analyses made by the Bio- logical Survey under suchmen as Judd, Beal, and McAtee (1900-1910). For Central and South American speciesthe field notes of Wetmore (1916, 1926), Wetmore and Swales (1931), and a few other careful observerswere invaluable. Functionally, the method of feedingis of even greater importance than the kind of food taken, and very close observation of birds in field and captivity has been necessary. I am deeply indebted to its designer,Mr. Victor Carbonara, for the use of a Sard 6x 20 binocular, invaluable at ranges down to four feet.
