Solution:

Please add missed class 'Sighting.class' to TestArchive, such as

   @Deployment
   public static Archive<?> createTestArchive() {
      return ShrinkWrap.create(WebArchive.class, "test.war")
            .addClasses(Bird.class, Sighting.class, BirdRegistration.class, Resources.class)
            .addAsResource("META-INF/test-persistence.xml", "META-INF/persistence.xml")
            .addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml")
            // Deploy our test datasource
            .addAsWebInfResource("test-ds.xml", "test-ds.xml");
   }
