Cuckoos ​Cuculidae

​about cuckoos in nw ohio

​Two species of cuckoo occur in Ohio: the Yellow-billed Cuckoo and Black-billed Cuckoo. They may winter as far south as central South America with some traveling as far north as southern Canada to breed. In Northwest Ohio in spring, cuckoos pass through primarily in the latter half of May, foraging in a variety of forests. In fall, passage is much more sporadic through the season, and the lack of encounters of Black-billed suggests a resistance to cross Lake Erie. 

On occasion, cuckoos will venture down to forest undergrowth following caterpillars and other insects; however, they primarily remain in the canopy, hiding in dense foliage. Because cuckoos aren’t particularly abundant during migration, their banding totals may not truly reflect the number of birds moving through as these birds tend to stay high and their larger size may impact their capture rate. Data on cuckoo sexes are unavailable as males and females are identical in plumage and nearly so in size. ​

Alpha Code: YBCU
Spanish: Cuco de Pico Amarillo
French: Coulicou à bec jaune

NW Ohio Status: Migrant, Breeding

Spring Migration Timing: Primarily third wave, with birds first appearing around the second week of May and the peak of total birds occurring May 18-30. 

​Fall Migration Timing: Fairly protracted with birds moving through the region mid-August into mid-October, and the peak of total birds occurring September 7-23.

Migration Habitat: Woodlands, thickets, and groves. YBCU primarily stay hidden among dense canopy foliage but will move lower into forest edge scrub-shrub and undergrowth.

Nightjars ​Caprimulgidae

​about nightjars in nw ohio

Two species of nightjar commonly occur in Northwest Ohio, with a third, mostly southern species occasionally making its way north. These aerial insectivores forage primarily at night, dusk, and dawn, capturing moths and other insects in their wide, gaping mouths. As an active forager of the dark, nightjars are extremely well camouflaged for daytime roosting on horizontal surfaces, seamlessly blending in with rotten logs and tree branches. 

Nightjars may arrive in Northwest Ohio as early as April, but primarily appear along the lake shore in early May. Due to their habitat preferences, the Eastern Whip-poor-will is the primary nightjar encountered during BSBO’s banding operations. Although a number of nightjars may be heard before sunrise, nightjar activity generally ceases before banding operations begin for the day.

Often overlooked as part of a rotting log, the bird has an overall camouflaged mottling of brown, gray, and limited rufous, with notably gray scapulars. In flight, males show white corners to the tail, while females have buff. ​

Spring Migration Timing: A secretive migrant. Some begin to appear by mid April, but peak migration occurs from April 30 through May 7.

​​Fall Migration Timing: Insufficient data to graph. 

Migration Habitat: In a variety of woodlands, birds are typically found on fallen logs, low branches, or directly on the ground. Exceptional camouflage allows the bird to blend in with the surrounding habitat.

Numbers may not reflect true abundance of birds as most EWPW activity (nocturnal foraging) ceases just before banding operations begin. ​

Hummingbirds ​Trochilidae

​about hummingbirds nw ohio

The Ruby-throated Hummingbird is Ohio’s only common hummingbird (with the occasional stray western species occurring rarely). These small, active birds are renowned for their bright iridescent feathers, high energy, and willingness to come to backyard feeders. Hummingbirds can be found in a variety of habitats during migration, but tend to favor areas with flowers. However, while they are famously known for consuming nectar and sugar-water, hummingbirds also feed on small insects, even plucking spiders and other captured prey from webs. 

Wintering primarily in southern Mexico and Central America, the Ruby-throated arrives in Northwest Ohio as early as late April, but makes its biggest pushes in May. During fall, as flowers become scarce, hummingbirds may become thinly dispersed across the landscape, and most depart the region by October.

Spring Migration Timing: Second into third wave, with males arriving in the region within the first week of May and the peak of total birds occurring May 15-25. 

​​Fall Migration Timing: Early, with the heaviest movements confined to September and most birds departing by October. Peak movement of total birds occurring August 31 through September 17.  

Migration Habitat: Semi-open areas and forest edges where flowers are present including forest clearings, scrub-shrub, urban parks, and backyards.

Probably some level of under-representation in data as research project is designed for larger songbirds and RTHU may pass through nets without being captured. With their slightly smaller size, males may pass through more frequently than females (possibly explaining their much lower numbers). ​
