Yesterday was a cold day for New Jersey. It was 28 °F (-2.2 °C) when I arrived at the refuge, and the temperature did not budge from that when I left after an hour and a half. During that time I saw mainly ducks, Mute Swans, Great Blue Herons, and Hooded Mergansers. All the white Egrets had migrated south.

However, many Yellow-rumped Warblers were chirping and feasting on Juniper Berries and I took the following photos of several of them. Their pale brown colors show that they were still immature birds perhaps born in 2023.
