Book Review:: How Birds Migrate

I finished reading How Birds Migrate by Paul Kerlinger just ahead of International Migratory Bird Day which is coming up on May 8th. Migration is an important topic for the urban environment as many cities have an enormous impact on bird migration and many cities, including Portland and Seattle, lay in a major flyway, which is the Pacific Flyway on the west coast.

Apparently a new edition of the book came out recently which is worth a look at because the edition I read was very dated in some places. The book has a lot of great information about bird migration as well as a lot of case studies, most of which are from the east coast and very few from the west coast unfortunately.

Bird Safe Building Updates

There are some new items to add to a previous post about bird safe building guidelines.

First, from the American Bird Conservancy comes news about proposed legislation that would put regulations on federal building construction.

Dusty Gedge & Biodiversity Ecoroofs

This week was a very exciting week in Portland, Oregon because the city brought in ecoroof expert, Dusty Gedge. Along with Stephan Brenneisen they are two of the leading experts in creating ecoroofs that are aimed at biodiversity instead of only stormwater management. Both have written many good articles and designed many roofs in the U.K. and Switzerland.

The city of Portland just finished off Ecoroof Portland month, which included an event two weeks ago with vendors and many speakers. This week included two talks with Dusty and an ecoroof design charrette that I was lucky enough to be invited to and participate in, also with Dusty. The city of Portland is really moving forward the biodiversity effort and now including incentives for building owners to install ecoroofs on their buildings.

Dusty Gedge is the co-founder of and has been instrumental in creating habitat…
