Frequently Asked Questions
How loud is the red throated grosbeak’s song?
The red throated grosbeak has a moderately loud song that carries well through its woodland habitats. Songs can be heard from over 200 feet away on a quiet morning.
What do red throated grosbeak chicks sound like?
Nestling red throated grosbeaks make loud raspy begging calls when hungry. These calls sound like harsh, buzzing “zreeeee” noises.
When do red throated grosbeaks migrate?
Most red throated grosbeaks migrate in April/May and September/October. During migration they may occasionally sing, but vocalizations are less frequent.
How can I attract red throated grosbeaks?
You can attract red throated grosbeaks to backyards by providing platform feeders stocked with sunflower seeds and fruits. Having trees and brush for nesting can also draw them in.
Are red throated grosbeak songs unique to each bird?
Recent research shows that male red throated grosbeaks likely have an individiual song “signature” that allows them to distinguish between one another.
This individual variation suggests their songs play a role in recognition between specific birds, similar to human voices.
Color Variations
The red throated grosbeak shows some subtle geographic variation in plumage color across its range. These include:
- Western males have a brighter red throat patch
- Midwest males have deeper red on the head and breast
- Females are duller gray-brown overall in the east
Understanding these subtle differences can aid identification of subspecies in regions where their ranges overlap.
Plumage Changes by Season
Red throated grosbeaks also show changes in plumage color through the year as feathers fade and are replaced. These include:
- Brighter red throats in spring as feathers are fresh
- Faded, duller plumage in late summer prior to molting
- Brighter, bolder colors after completing their annual molt in early fall
Being aware of these seasonal differences can prevent misidentifying faded birds.
Nesting and Reproduction
The nesting habits and behaviors of the red throated grosbeak include:
- Nests built by females 3-20 feet above ground
- Cup nests constructed from twigs and lined with grass
- 2-5 pale blue eggs laid
- Only female incubates eggs for 12-14 days
- Young fledge the nest at 10-14 days old
Understanding the red throated grosbeak’s breeding cycle helps know when to expect peak singing activity by males.
