Record of Anthophora (Clisodon) terminalis in a wooden trap-nesting block and comparison to available nesting information (Hymenoptera: Apidae)

Bee nesting substrate choice can influence habitat use, conservation effort efficacy, and population or landscape-use modeling, but information on nesting sites are often scattered in the literature. Here we bring together the available information on nests of a widespread bee, Anthophora (Clisodon) terminalis Cresson, and describe an unusual new nesting substrate use for this species

First Records of Stelis permaculata Cockerell (Hymenoptera: Megachilidae) in Minnesota, United States of America and Manitoba, Canada

Abstract New records are reported for the cleptoparasitic bee Stelis permaculata Cockerell (Hymenoptera: Megachilidae) from Minnesota, United States of America and Manitoba, Canada. Minnesota records come from trap-nests, which also collected the host, Heriades carinata Cresson

Minnesota State Records for Osmia georgica, Megachile inimica, and Megachile frugalis (Hymenoptera, Megachilidae), Including a New Nest Description for Megachile frugalis Compared with Other Species in the Subgenus Sayapis

In this note, we report the first Minnesota state records of Osmia (Helicosmia) georgica Cresson 1878,Megachile (Sayapis) inimica Cresson 1872, and Megachile (Sayapis) frugalis Cresson 1872, which were collected in 2018. We also provide the first description of the nest structure of M. frugalis. All three species typically have more southern distributions. The nest of M. frugalis shows similar structure to other species in the subgenus Sayapis Titus, such as M. inimica and M. pugnata, particularly in that the longitudinal nest cell walls lack a lining of leaf pieces, and the cell partitions are made from a layer of leaf pieces followed by a layer of masticated vegetation and soil particles

FIRST COHORT OF MIGRATORY WHOOPING CRANES REINTRODUCED TO EASTERN NORTH AMERICA: THE FIRST YEAR AFTER RELEASE

We describe the post-release movements and survival of the first cohort in the eastern migratory whooping crane (Grus americana) reintroduction from release the first winter through return the second winter. Six cranes were led behind ultralight aircraft from Necedah National Wildlife Refuge (NWR), Central Wisconsin, to Chassahowitzka NWR, Gulf Coast of Florida. After release in Florida, 1 of these cranes and another transported there by truck were killed by bobcats (Lynx rufus). The winter management protocol was modified and no further predation occurred. The 5 remaining cranes migrated unassisted back to Necedah NWR in spring, left the refuge during a spring wandering period, and then 4 returned to Necedah NWR to spend the summer. All 5 birds migrated back to Florida to winter, and 4 returned at least initially to Chassahowitzka NWR or adjacent salt marsh before 3 dispersed to suitable habitat inland. One yearling remained at Chassahowitzka NWR with the newly released juveniles from the second year’s release. Of the other 4 birds, 2 wintered separately with sandhill cranes (G. canadensis) in northern Florida, and 2 wintered as a pair on ranchland 62 km from the original winter release site. After the bobcat predation problem was solved, the subsequent survival, migration, summering, and wintering of these reintroduced whooping cranes were favorable for a successful reintroduction
