Avian Vocalizations Center : What We're About Attracting Wildlife Feeding Wildlife Wildlife feeding can be expensive. Compare prices at your local nursery, feed mill, and specialty store. Seed is often cheaper if you purchase it in larger quantities. Feeding Menu Click on the plus (+) sign to expand each category. Winter Feeding Sunflower Seeds: There is no such thing as a simple sunflower seed: you'll have to make a choice between black oil, striped, hulled seeds, and chips. Summer Feeding Add the following offerings to your bird seed during the summer to attract new species that prefer these foods. Note: Insect infestations in bird seed can be a nuisance during the warmer months. Sugar Water: Hummingbirds are the best known of the sugar water consumers. Habitat Habitat is the total environment in which living things exist -- the home, the natural abode. You can plant your yard to be suitable wildlife habitat. Trees are valuable to wildlife as sources of food for certain periods during the year. Many native Ohio shrubs are useful for attracting birds.
eBird Sam Murray, June eBirder of the Month Please join us in congratulating Sam Murray of Augusta, GA, winner of the June 2017 eBird Challenge, sponsored by Carl Zeiss Sports Optics. Our June winner was drawn from eBirders who submitted 15 or more eligible checklists containing at least one breeding code in June. Sam’s name was drawn randomly from the 1,769 eligible eBirders who achieved the June challenge threshold. Sam will receive new ZEISS Conquest HD 8×42 binoculars for his eBirding efforts. eBird Illustrated Checklists are here! You can now view a digital bird guide for any hotspot or region in the world: an Illustrated Checklist. eBird Server Maintenance on July 20 – website unavailable 03:30-08:00ET All of eBird will be unavailable on July 20 between 03:30-08:00ET (08:30-13:00GMT), due to regularly scheduled server and database maintenance.

Online bird guide, bird ID help, life history, bird sounds from Cornell Birdtree.org (Phylogenetic Mapping) General approach Our tree construction approach combines relaxed clock molecular trees of well-supported avian clades with a fossil calibrated backbone with representatives from each clade. It is neither a typical supertree (i.e. a combination of existing trees) nor a supermatrix approach (a single analysis applied to the entire genetic data matrix). We follow four steps: Each species is assigned to one of 158 clades; Relaxed-clock trees are generated for each clade; Species without genetic information are partially constrained within their clade based on a combination of consensus trees from step 2 and taxonomic information. Expanded methods: Jetz et al. 2012, Supplementary Methods section 1.1.1 Backbone trees We constructed and dated distributions of “backbone” trees each containing 158 tips.

Migratory Birds and Flyways The BirdLife Flyways Programme is working on the ground to protect chains of Important Bird & Biodiversity Areas (IBAs) that are critical for migratory birds, and to reduce threats along these routes. Analyses of the data that BirdLife compiles for the IUCN Red List show that migratory birds have become more threatened since 1988, with 33 species moving to more serious threat categories, and just six improving in status. Many of these declining species were once common, and their arrivals and departures are significant cultural events throughout much of the world. Their disappearance from the landscape was unthinkable 30 years ago, but is now a real prospect without concerted action. Case study: Palearctic-African migratory birds have suffered substantial declines. Birds know no borders The Bar-tailed Godwit, Limosa lapponica, undertakes one of the avian world’s most extraordinary migratory journeys. Case study: Migrating birds know no boundaries Objectives Protecting and restoring key sites
