Introduction
I am interested in the resilience of urban ecosystems, in particular the interactions of native and non-native species. My primary focus is how birds use urban natural areas, specifically food resources available in urban areas and the role of non-native fruiting plant species in the diets of birds. I've also done substantial work on the distribution of Odonata and other insects. I also have a keen interest in coffee agroforestry systems, and their role in biodiversity.

Little is known about how landbirds use urban habitats as migratory stopovers despite increasing urbanization in North America and the importance of the migratory period to annual survival of birds. I examined 15 years of autumn stopover data for three species of migratory Catharus thrushes from an urban natural area in metropolitan Detroit, Michig...

The buckthorns Rhamnus cathartica and Frangula alnus are nonnative invasive species in North America whose seeds are primarily dispersed by birds. This paper presents the first major compilation of the bird species that eat R. cathartica and F. alnus in eastern North America, where these buckthorns are most invasive and have few common congeners. U...

Ophiogomphus howei Bromley is a rare North American dragonfly, given a global conservation rank of Vulnerable by NatureServe. This species inhabits localized stretches of a limited number of typically undisturbed, high-quality, forested rivers in two disjunct regions in North America. We describe a new population in between the known ranges from an...

BULLETIN OF AMERICAN ODONATOLOGY In June 2021, two female Somatochlora hineana (Hine's Emerald) were collected in Oceana County, Michigan, a location > 100 km from the nearest known populations. This is a region apparently lacking sizable areas of characteristic S. hineana habitat: fens or similar calcareous wetlands with shallow soils over dolomit...

Monitoring introduced species is important because of possible effects on native species and ecosystems. Here, we report on European Goldfinch observations from North America between 2001–2021, focusing on a population in the western Great Lakes region. We compiled over 7000 records of European Goldfinches from multiple sources for this time period...

I document observations of birds feeding on the larvae of the leaf-mining moth Phyllonorycter emberizaepenella (Gracillariidae) in Michigan, USA. The larvae were feeding on Amur honeysuckle, Lonicera maackii (Caprifoliaceae), a non-native plant that has not been documented as a host for any species of Gracillariidae in North America, and which has...

Fruit size, seed load, and seed size are considered important metrics influencing fruit choice and subsequent seed dispersal by birds. I describe these traits for 37 plant taxa in southeast Michigan, based on measurements of over 5,800 fruits and 8,000 seeds. I also provide nearly 200 measurements for the same taxa found in the literature. These da...

Cordulegaster erronea Hagen inSelys (Tiger Spiketail) has been included on the list of Michigan Odonata based on one specimen collected in 1934. In 2016, the species was found in Kalamazoo County, Michigan. It is the least abundant Cordulegasterspecies in Michigan, and the habitat requirements in Michigan are compared with known C. erronea habit...

Yellow-shafted Flickers (Colaptes auratus auratus subspecies group of the Northern Flicker) occasionally have orange to red flight feathers in eastern North America far from the hybrid zone with the Red-shafted Flicker (C. a. cafer subspecies group). Blocks of feathers of anomalous color tend to show bilateral symmetry and may differ from one year...

An Alleghany River Cruiser, Macromia alleghaniensis Williamson, collected in Cass County, Michigan on 18 June 2014, represents the first record of the species for the state, as well as the northernmost unequivocal record in North America. Other records north of 40° latitude are clarified and discussed.

Ninety species of Odonata are now verified by specimens for Wayne County, MI, a highly urbanized county in the southeastern corner of the state. This total represents 54% of the total number recorded in the state of Michigan. Thirty-three species not previously reported from Wayne County have been collected since 2000, despite a long history of col...

Beginning in late summer 2010, the Neotropical dragonfly Tramea calverti Muttkowski, striped saddlebags, was observed in a major northward movement in eastern North America. This species appeared for the first time in three Great Lakes states and Canada (Ontario). A specimen from Michigan is the first and only voucher in the Great Lakes.

Two band-winged dragonlets, Erythrodiplax umbrata (Linnaeus), collected in Wayne County, Michigan on 6 October 2007 represent the first records for this genus and species in the state, as well as the northernmost record for the species.

Isodontia elegans (Smith) (Hymenoptera: Sphecidae), one of the "grass-carrying wasps," previously known only from the western U.S., is now reported from southeastern Michigan, and appears to have spread across the eastern half of the United States in a relatively short period.

Libellula vibrans Fabricius (Odonata: Libellulidae) is a large dragonfly previously known in Michigan only from sight or literature records. In 2005, two small populations were found in Wayne County, Michigan. ____________________ Libellula vibrans Fabricius (Odonata: Libellulidae), the Great Blue Skim-mer, is not mentioned in historical lists of M...

On 10 September 1993, I was tending the banding nets for the Rouge River Bird Observatory (RRBO) at the University of Michigan-Dearborn, Wayne Co., Michigan. On my way down the net lanes, I noticed a bird struggling in the weeds. It was a Swainson's Thrush (Catharus ustalatus) thoroughly caught by the wings in the seed pods of a clump of enchanter'...
