Why doesn't our saltmarsh sparrow like the new invasive grasses in her habitat?

• She can't eat it.

• She can't build her nest with it.

• It is too green.

Answer explanation

NEST DESCRIPTION

The female constructs the nest, which is a simple, bulky cup of marsh grasses and reeds, supported by stems of marsh plants at the sides and often by mats (thatch) of saltmeadow cordgrass below. Females sometimes build a partial dome over the top of the nest. Males don’t help raise young; females normally approach the nest from some distance on the ground, through tunnels beneath the thatch of cordgrass. Nests average 2.8 inches tall by 3.4 inches across, with the interior cup 2 inches across and 1.5 inches deep.

As the sparrow flew to find a better marsh, what did she do?

• She ate berries that she had never tried.

• She joined a flock of other sparrows.

• She dropped scat that was full of seeds.

• She hurt her wing.

Answer explanation

Bird scat plays an important role in spreading seeds!

When eating plant seeds, the birds digest the seeds and pass them out in their droppings.

The fecal material gives seeds a dose of fertilizer high in nitrogen , which can help fuel growth of the new plants!

What saved our sparrow from crashing into the house windows?

• polka dots

• stickers

• the dashed line

Answer explanation

You can purchase stickers to save birds from crashing into your windows...

BUT it's so much more fun to make your own!

Leashing your dog outdoors will prevent them from chasing or attacking wild animals as well as disrupting their natural habitats. Just as important, leashing your dog helps to eliminate being chased by potentially dangerous wildlife towards you.

Choose all the reasons why the scientist captured our saltmarsh sparrow.

• take measurements of her

• attach a tag to her leg

• feed her medicine

Answer explanation

This is Jessica Szpila, a wildlife and conservation biologist. She and others are working hard to motivate people to make changes to prevent the loss of the saltmarsh swallow habitat.

Bird tagging or banding aids in scientific research to identify population, migration, behavior, social structure, life-span, survival rate, and nesting.
