Birds and birding news
  • Birders are encouraged to report the vocalizations of female birds to eBird (preferably with recordings) to support the Female Bird Song Project.
  • Male and female songbirds do not have enough differences in their syringeal muscles to account for differences in male and female songs.
  • Studies of Hermit Thrush songs have found differences based on geography: Hermit Thrushes in the East sing a wider range of frequencies at the start of their songs, while ones in the West sing a longer opening sustained note.
  • Ruddy Turnstones migrating along the East Asian-Australasian Flyway are arriving at their breeding grounds a day earlier than in the past.
  • A large extinct species of megapode, Progura gallinacea, was among several evaluated in a recent review of megapode taxonomy.
  • At least five states have citizen science programs that ask mail carriers to count game species, such as quail or rabbits, along their delivery routes.
  • A birder was followed by Black Vultures after he went near a carcass they had been scavenging. 
  • Piping Plovers are nesting at Island Beach State Park.
  • Late-nesting birds and bees face a greater threat of habitat damage by the time they nest.
  • The reflecting pool in front of the Lincoln Memorial will be drained because 80 ducks died from a parasite present in its waters.
  • A slideshow shows Bald Eagles  scavenging at the docks in Dutch Harbor, Alaska.

Environment and biodiversity
  • Urban heat islands are already deadly during summer heat waves, and they are likely to get worse because of climate change.
  • Secretary Zinke recommended reducing the size of Bears Ears National Monument (presumably to just a handful of archaeological sites) after a full review of recent national monument designations is complete.
  • The designation of Bears Ears as a national monument accomplishes one of the main goals of the Antiquities Act: protection of archaeological resources from looting and vandalism.
  • Some of the monuments under threat have productive fossil beds. 
  • Revocation of national monument designations could also endanger migrations along America's unique wildlife corridors.
  • A Canadian climate change study had to be postponed because of hazardous sea ice conditions caused by climate change.
  • Fossil beetles found in the La Brea Tar Pits show that California has had a mostly stable climate for the past 50,000 years. 
  • The Trump administration cancelled a rule intended to reduce the number of whales and sea turtles tangled in fishing nets.
  • A new barrier system should prevent the 1D landfill in Kearny from leaching pollutants into the Passaic River in the Meadowlands.
  • American Shad have returned to New Jersey's Musconetcong River after removal of the Hughesville Dam. More dam removals are likely to open more of the watershed to migratory fish.
  • The New York Botanical Garden is producing a checklist of plants in New York City.
