Showing Hierarchical Data in a TreeView

Hi:

I declared a TreeView in xaml bound to a Hierarchical object in memory, but it doesn't show the info.Here's the object structure:

public class Animals {
    public string Name { get; set; }
    public List<Kind> Kinds { get; set; }
}

public class Kind {
    public string Name { get; set; }
    public List<Animal> Animal { get; set; }
}

public class Animal {
    public string Name { get; set; }
}

I initialize it in the Window's constructor:

public partial class MainWindow : Window {
    public MainWindow() {
        InitializeComponent();
        var animals = new Animals {Name = "Animals Kingdom", Kinds = new List<Kind>()};

        var kind = new Kind {Name = "Vertebrae", Animal = new List<Animal>()};
        var animal = new Animal { Name = "Bear" };
        kind.Animal.Add(animal);
        animal = new Animal() { Name = "Tiger" };
        kind.Animal.Add(animal);
        animal = new Animal() { Name = "Lion" };
        kind.Animal.Add(animal);

        animals.Kinds.Add(kind);

        kind = new Kind { Name = "Invertebrae", Animal = new List<Animal>() };
        animal = new Animal { Name = "Fly" };
        kind.Animal.Add(animal);
        animal = new Animal() { Name = "Grasshopper" };
        kind.Animal.Add(animal);
        animal = new Animal() { Name = "Spider" };
        kind.Animal.Add(animal);

        animals.Kinds.Add(kind);
    }
}

And I declare it in xaml:

<Window.Resources><local:Animals x:Key="MyList"/><HierarchicalDataTemplate DataType = "{x:Type local:Animals}"
                            ItemsSource = "{Binding Path=Kinds}"><TextBlock Text="{Binding Path=Name}"/></HierarchicalDataTemplate><HierarchicalDataTemplate DataType = "{x:Type local:Kind}"
                            ItemsSource = "{Binding Path=Animal}"><TextBlock Text="{Binding Path=Name}"/></HierarchicalDataTemplate><DataTemplate DataType="{x:Type local:Animal}"><TextBlock Text="{Binding Path=Name}"/></DataTemplate></Window.Resources><DockPanel><TreeView><TreeViewItem x:Name="tree" ItemsSource="{Binding Source={StaticResource MyList}}" Header="Animals" /></TreeView></DockPanel>

The TreeView appears empty:

Any suggestions.
