Create a variable named matchingBirds and assign it a LINQ query on the birds variable that have the same Color property as the mysteryBird object. In the query, return an anonymous type with a property named BirdName and assign to it the Name property of the birds.
var birds = new[]
{
new { Name = "Pelican", Color = "White" },
new { Name = "Swan", Color = "White" },
new { Name = "Crow", Color = "Black" }
};
var mysteryBird = new {Name="MysteryBird", Color = "White", Sightings =3 };
var matchingBirds = from b in birds where mysteryBird.Color == "White" select new { BirdName = b.Name,BirdColor=b.Color};

condition: where mysteryBird.Color == "White"
. The mysteryBird color is white, so this boolean expression will always be true, which is why we end up with all 3 birds in our result, rather than filtering it down to just 2.
What you want is to check if each bird, b
, in the loop has the same color as the mysteryBird: mysteryBird.Color == b.Color
var birds = new[]
{
new { Name = "Pelican", Color = "White" },
new { Name = "Swan", Color = "White" },
new { Name = "Crow", Color = "Black" }
};
var mysteryBird = new {Name="MysteryBird", Color = "White", Sightings =3 };
var matchingBirds = from b in birds where mysteryBird.Color == b.Color select new { BirdName = b.Name,BirdColor=b.Color};
