I've checked my code a few times, still getting a console error, Is something wrong with the flickr API?

$(document).ready(function(){         
  $("button").click(function() {    
    $("button").removeClass("selected");
    $(this).addClass("selected");

    var flickerAPI = "http://api.flickr.com/services/fees/photos_public.gne?jsoncallback=?";
    var animal = $(this).text();
    var flickrOptions = {
      tags:animal,
      format: "json"
    };
    function displayPhotos(data) {
      var photoHTML = "<ul>";
      $.each( data.items, function (i, photo) {
        photoHTML += "<li class='grid-25 tablet-grid-50'>";
        photoHTML += "<a href='" + photo.link + "' class='image'>";
        photoHTML += "<img src='" + photo.media.m + "'></a></li>";
      });
      photoHTML += "</ul>";
      $("#photos").html(photoHTML);
    }
    $.getJSON(flickerAPI, flickrOptions, displayPhotos);
  });
});     // end ready
