BATON ROUGE, La. — State wildlife officials say a $100,000 grant and free access to extensive lands along Louisiana’s coast will help fill the gaps in a series of solar-powered towers to track radio-tagged migratory birds.

Department of Wildlife and Fisheries ornithologist Michael Seymour says ConocoPhillips is giving the money and access to coastal property for the project.

The department, the Barataria-Terrebonne National Estuary Program and Louisiana Wildlife and Fisheries Foundation have installed 13 receiver stations since spring 2016.

They plan a line of 32 stations by next July, and say that will provide nearly seamless coverage along the coast.

It’s part of an international collaboration called the Motus Wildlife Tracking System . The system tracks birds, bats and even large insects to which researchers have fixed tiny “nano-tags” that broadcast several signals a minute.
