Eagle Friday – Will we have eggs?
We do not know if Rosa will lay eggs this year. With the disappearance of Martin in early December 2023, V2 arrived at the Dulles Greenway Eagles nest on December 11, 2023. Rosa and V2 regularly do nest work together. This week V2 has brought lots of “fluff” (bedding) bundles to the nest as well as new sticks, with Rosa helping too. It appears they are preparing the nest but will there be eggs?
The American Eagle Foundation tells us that female eagles “may have 3 two week windows throughout a breeding season where she is fertile.” We believe the fertile season here is in January and February. On camera, we saw Rosa and V2 successfully mate on December 30, January 1, 2, 3, and two matings today (January 5). We have no way of knowing if other mating events have taken place. We will continue to observe Rosa and V2’s behavior in the coming weeks to look for signs of possible egg laying:
- Increased rate of mating
- Spending a lot of time standing on the nest
- Forming the nest bowl
- Trying out the nest bowl
- Bringing in more soft nesting material
- Turning in the nest bowl
For the last two years, Rosa has laid eggs at the beginning of February.
The Dulles Greenway Eagles Team is glad that it appears Rosa has a new mate but we continue to mourn the disappearance of Martin. We may never know what happened to him but he will remain in our hearts. Here is our Tribute to Martin: https://www.youtube.com/watch?v=5yNuSy62i-8&t=362s
