Over the last 60 years, bluebird populations have steadily declined for a number of reasons including a lack of natural cavities in trees and snags and increased competition for nesting sites and food from non-native bird species. Nest boxes are an easy way to help bluebirds increase their population numbers. Nest boxes are specifically designed to create an appropriate sized nest cavity for bluebirds, and when positioned and maintained properly, bluebirds will readily use them and fledge numerous chicks throughout the summer.
As part of its biodiversity program, Bacardi Bottling Corporation in Jacksonville, Florida, has restored five acres of native warm season grasses on its property, and installed a dozen bluebird nest boxes within the restoration area. Audubon Florida staff recently joined Sally Cannon, Eric Hearn, Jen Lishen and Denise Guillet of Bacardi during their weekly Nest Watch to monitor their bluebird boxes. Some of the nest boxes were empty, but many had the beginnings of nests or nests with eggs. There was also an abundance of grasshoppers and other insects, otherwise known as bluebird food, living amongst the newly restored grassland.
Audubon Florida is happy to see many corporations creating environmental stewardship and sustainability policies in their corporate strategies. Strategies including energy and water savings and land restoration are simple ways for corporations to generate a softer impact on the environment they depend upon. We encourage you to learn more about the environmental policies of the corporations you frequent – what you learn may surprise you.
